How many moles are in 5.60 x 1027 molecules of carbon monoxide? with a bridge Please answer quickly I have to turn it in soon
Answer:
9302 moles of CO contain 5.60×10²⁷ molecules
Explanation:
We solve this with Avogadro's number.
NA = 6.02×10²³
This number states the how many particles are in 1 mol of anything.
1 mol of atoms contains 6.02×10²³ atoms
1 mol of molecules contains 6.02×10²³ molecules.
We apply a rule of three:
6.02×10²³ molecules are contained in 1 mol of CO
Then, 5.60×10²⁷ molecules may be contained in (5.60×10²⁷ . 1) / 6.02×10²³
= 9302 moles
Organisms that are made up of prokaryotic cells are NOT ____________.
Question 3 options:
Bacteria
Multicellular
Simpler than organisms made up of Eukaryotic celled organisms
All of these are true about prokaryotic cells
Answer:
Multicellular
Explanation:
Prokaryotic cells are unicellular because the do not have a nucleus and lack organelles, while eukaryotic cells do have a nucleus, have organelles, and are are multicellular. :)
Organisms that are made up of prokaryotic cells are NOT
Multicellular.
Classification of Organisms based on cellular organisation.Living organisms can be classified based on their cellular organisation.
Organisms that are made up of one cell are known as unicellular organisms.
Organisms that are made up of more than one cell are known as multicellular organisms.
A prokaryote is an organism that lacks distinct nucleus while eukaryote is an organism that possess a nucleus that is enclosed in a nuclear envelope.
While prokaryotes are always unicellular organisms, eukaryotes can be either unicellular or multicellular.
Therefore, organisms that are made up of prokaryotic cells are not multicellular.

which of the following has a mass of 10.0g
Answer: 0.119 mole of Kr has a mass of 10.0 g
Explanation:
The complete Question was ontained online, albeit, it was incomplete, even from the online source. But the solution is possible based on the part of the question obtained.
Complete Question
Which of the following Noble Gases has a mass of 10.0 g?
A. 2.02 mol Ne B. 0.119 mol Kr C.
Solution
Number of moles = (Mass)/(Molar Mass)
Mass = (Number of moles) × (Molar mass)
Checking the options, one at a time,
A. 2.02 moles of Neon
Number of moles = 2.02 moles
Molar Mass of Neon = 20.1797 g/mol
Mass = 2.02 × 20.1797 = 40.762994 g ≠ 10.0 g
Not the answer.
B. 0.119 moles of Krypton
Number of moles = 0.119 moles
Molar Mass of Krypton = 83.798 g/mol
Mass = 0.119 × 83.798 = 9.971962 g ≈ 10.

what is the mass in kilograms of 25L of hydrophosphoric acid?
Answer:
0.0345kg is the mass of 25L of the sample
Explanation:
Hydrophosphoric acid, H₃P = Phosphine has a density of 1.38g/L.
To solve this question we need to convert the volume of the gas to mass in grams as first and then to kilograms as follows:
Mass in grams:
25L * (1.38g / L) = 34.5g
Mass in kilograms:
34.5g * (1kg / 1000g) = 0.0345kg is the mass of 25L of the sample

Hund's rule tells us that 1) any orbital in a given subshell must first be occupied by a single electron before being occupied by a second electron and 2) the electrons in a singly occupied orbital all have the same spin.
Diagram I follows both 1 and 2; there are no prematurely-filled orbitals (boxes), and all the singly-filled 2p orbital have the same spin (the arrows are all pointing up). So, diagram I follows Hund's rule and is correct.
Diagram II violates 1: the first box in the 2p subshell is doubly filled while there's still a vacant orbital. That second electron in the first box should be in the third box and pointing upward for diagram II to be correct. Thus, diagram II violates Hund's rule and is incorrect.
Diagram III follows rule 1 but violates rule 2: While every 2p orbital is singly filled, they do not all have the same spin. In the second box, the arrow is pointing down while the arrows in the other two boxes are pointing up. Thus, diagram III violates Hund's rule and is incorrect.
So, of the diagrams given, II and III do not follow Hund's rule and thus are incorrect.

Calculate the concentration of a solution of sodium chloride if 15g are added to water to make a 200cm³ solution. The answer shoulsd be in units of g/dm³.
Answer:
75 g/dm³
Explanation:
The following data were obtained from the question:
Mass of solute (NaCl) = 15 g
Volume of solution = 200 cm³
Concentration (in g/dm³) =?
Next, we shall convert 200 cm³ to dm³. This can be obtained as follow:
1000 cm³ = 1 dm³
Therefore,
200 cm³ = 200 cm³ × 1 dm³ / 1000 cm³
200 cm³ = 0.2 dm³
Thus, 200 cm³ is equivalent to 0.2 dm³.
Finally, we shall determine the concentration of the solution as follow:
Mass of solute (NaCl) = 15 g
Volume of solution = 0.2 dm³
Concentration (in g/dm³) =?
Concentration (in g/dm³) = mass / volume
Concentration (in g/dm³) = 15 g /0.2 dm³
Concentration (in g/dm³) = 75 g/dm³

When ethane (C2H6) burns, it produces carbon dioxide and water:
2C2H6(g)+7O2(g)→4CO2(g)+6H2O(l)
How many moles of water will be produced when 3 moles of ethane are burned?
3 moles
6 moles
9 moles
12 moles
Answer:
6 moles
Explanation:
According to stoichiometry and given chemical equation 2C₂H₆(g)+7O₂(g)→4CO₂(g)+6H₂O(l), 9 moles of water are produced when 3 moles of ethane are burned.
What is stoichiometry?Stoichiometry is the determination of proportions of elements or compounds in a chemical reaction. The related relations are based on law of conservation of mass and law of combining weights and volumes.
Stoichiometry is used in quantitative analysis for measuring concentrations of substances present in the sample.It is important while balancing chemical equations.
In the given problem , as 2 moles of ethane produce 6 moles of water so according to stoichiometry
∴ 3 moles of ethane will produce 3×6/2=9 moles
Thus, 9 moles of water are produced when 3 moles of ethane are burned.

How many moles of BH3 are synthesized when 27.0 moles of H2 completely react?
Answer: 18.0 moles of [tex]BH_3[/tex] will be produced when 27.0 moles of [tex]H_2[/tex] completely react.
Explanation:
The balanced chemical equation is:
[tex]2B+3H_2\rightarrow 2BH_3[/tex]
According to stoichiometry :
3 moles of [tex]H_2[/tex] produce = 2 moles of [tex]BH_3[/tex]
Thus 27.0 moles of [tex]H_2[/tex] will produce=[tex]\frac{2}{3}\times 27.0=18.0 moles[/tex] of [tex]BH_3[/tex]
Thus 18.0 moles of [tex]BH_3[/tex] will be produced when 27.0 moles of [tex]H_2[/tex] completely react.
