According to ideal gas equation, there are 271472.7 moles of gas present in a gas trapped within a 37.0 L vessel at 80.0°C at a pressure of 2.50 atm.
What is mole?Mole is defined as the unit of amount of substance . It is the quantity measure of amount of substance of how many elementary particles are present in a given substance.
It is defined as exactly 6.022×10²³ elementary entities. The elementary entity can be a molecule, atom ion depending on the type of substance. Amount of elementary entities in a mole is called as Avogadro's number.
It is widely used in chemistry as a suitable way for expressing amounts of reactants and products.For the practical purposes, mass of one mole of compound in grams is approximately equal to mass of one molecule of compound measured in Daltons .Molar mass has units of gram per mole . In case of molecules, where molar mass in grams present in one mole of atoms is its atomic mass.

An object with a mass of 3 kg has a momentum of 75 kg•m/s. What is the velocity?
Answers
Answer:
the velocity is 25 m/s
Explanation:
The computation of the velocity is shown below:
As we know that
Magnitude of Momentum = (mass) × (speed)
75 kg. m/s = 3 kg × speed
So, the speed is
= 75 ÷ 3
= 25 m/s
hence, the velocity is 25 m/s
List and Describe the two groups of clastic sedimentary rock.
Answers
Answer:
Clastic sedimentary rocks are formed from rock fragments or clasts; chemical sedimentary rocks precipitate from fluids, and biochemical sedimentary rocks form as precipitation from living organisms.
Sedimentary rock is classified into two groups based on how they form. They are clastic and chemical. Clastic sedimentary rock is formed as bits of weathered rock become cemented together. Because all kinds of rock are subject to weathering many different minerals can make up this group of rocks.

How many bases of RNA represent an amino acid?
Answers
Answer:
three bases
Genetic experiments showed that an amino acid is in fact encoded by a group of three bases, or codon.
Explanation:
Hope this helps
In the given question, three bases of RNA represent an amino acid.
RNA (ribonucleic acid) is a molecule that plays an important role in protein synthesis. It carries genetic information from DNA to ribosomes, where it is used to direct the assembly of amino acids into proteins.
The genetic code is the set of rules by which the sequence of nucleotides in DNA or RNA is translated into the sequence of amino acids in a protein. The code is based on the sequence of three nucleotides, known as a codon, which specifies a particular amino acid.There are 64 possible codons, but only 20 amino acids that are used to build proteins. This means that some amino acids are specified by more than one codon. For example, the amino acid leucine can be specified by six different codons: UUA, UUG, CUU, CUC, CUA, and CUG.Therefore, three RNA bases represent an amino acid.

1. An incline plane is a flat plan put at a positive angle with the ground (assuming the ground is horizontal)
2. Work equals force times distance. And since the hypotenuse of a triangle (the ramp) is longer than the opposite side (equivalent to lifting an object vertically), the increased distance decreases the force needed to do a certain amount of work.
3. We usually use incline planes to elevate large objects. Since it takes less force to move certain things up inclines rather than picking them up, it is much simpler to move an object up an incline.
4. You could decrease the force by making the plane's angle with the ground smaller.
5. I don't know; I wasn't in your class :)
6. Ramps, wheelchair entrances, inclined rooves etc.
7. No. A plane has to be relatively flat; therefore stairs are neither a plane, nor an inclined plane.

At what temperature would a 1.30 m NaCl solution freeze, given that the van't Hoff factor for NaCl is 1.9? Kf for water is 1.86 ∘C/m .
Answers
Answer:
-4.59°C
Explanation:
Let's see the formula for freezing point depression.
ΔT = Kf . m . i
ΔT = Freezing T° of pure solvent - Freezing T° of solution
Kf = Freezing constant. For water if 1.86°C/m
m = molality (moles of solute in 1kg of solvent)
i = Van't Hoff factor.
0°C - Freezing T° of solution = 1.86°C /m . 1.30m . 1.9
Freezing T° of solution = - (1.86°C /m . 1.30m . 1.9)
Freezing T° of solution = - (1.86°C/m . 1.30m . 1.9) → -4.59°C
NaCl → Na⁺ + Cl⁻
If 100 ml of a 0.5 M HCI Solution is diluted with water to 1000ml, what is the new concetration?
Answers
Answer:
[tex]0.05\ \text{M HCl}[/tex]
Explanation:
[tex]V_1[/tex] = Initial volume = 100 mL
[tex]V_2[/tex] = Final volume = 1000 mL
[tex]M_1[/tex] = Initial concentration = 0.5 M
[tex]M_2[/tex] = Final concentration
We have the relation
[tex]\dfrac{M_1}{M_2}=\dfrac{V_2}{V_1}\\\Rightarrow M_2=M_1\dfrac{V_1}{V_2}\\\Rightarrow M_2=0.5\times \dfrac{100}{1000}\\\Rightarrow M_2=0.05\ \text{M HCl}[/tex]
The new concentration is [tex]0.05\ \text{M HCl}[/tex].
