A coin is 3.00% Cu by mass. If the mass of the coin is 4.0561g, how many moles of Cu does it contain
Answer:
4.0561×0.03÷63.5= 0.001916 mol cu
A coin is 3.00% Cu by mass. If the mass of the coin is 4.0561g, moles of Cu does it contain 0.001916 mole of Cu.
What is mass ?It is the most fundamental characteristic of matter and one of the fundamental quantities in physics.
Mass is a term used to describe how much matter is there in a body. The kilogramme is the SI unit of mass (kg). A body's mass does not alter at any point in time.
Given mass of coin = 4.0561g , moles =? , Cu by mass= 3.00%
4.0561×0.03÷63.5= 0.001916 mole Cu.
Thus, A coin is 3.00% Cu by mass. If the mass of the coin is 4.0561g, moles of Cu does it contain 0.001916 mole of Cu.

A tank of gas is found to exert 8.6 atm at 38°C. What would be the required
temperature to change the pressure to standard pressure?
Answer:
36.2 K
Explanation:
Step 1: Given data
Initial pressure of the gas (P₁): 8.6 atmInitial temperature of the gas (T₁): 38°CFinal pressure of the gas (P₂): 1.0 atm (standard pressure)Final temperature of the gas (T₂): ?Step 2: Convert T₁ to Kelvin
We will use the following expression.
K = °C +273.15
K = 38 °C +273.15 = 311 K
Step 3: Calculate T₂
We will use Gay Lussac's law.
P₁/T₁ = P₂/T₂
T₂ = P₂ × T₁/P₁
T₂ = 1.0 atm × 311 K/8.6 atm = 36.2 K

What usually happens to the solubility of gas as temperatures decreases?
Answer:
the solubility of the gas increases
Explanation:
as the kinetic energy of a gaseous solute increases,its molecules has a greater chance of escaping the attraction of the solvent molecules and return to the gas phase..which lead to the solubility of the gas been Increase as the temperature decreased .

___Li + ___AlPO4 --> ___Al + ___Li3PO4
If 2.3 moles of Aluminum Phosphate are reacted, how many grams of Lithium Phosphate are produced?
Answer:
266.3 g
Explanation:
__Li + __AlPO₄ → __Al + __Li₃PO₄The balanced reaction is:
3Li + AlPO₄ → Al + Li₃PO₄First we convert 2.3 moles of AlPO₄ to moles of Li₃PO₄, using the stoichiometric coefficients:
2.3 mol AlPO₄ * [tex]\frac{1molLi_3PO_4}{1molAlPO_4}[/tex] = 2.3 mol Li₃PO₄Then we convert Li₃PO₄ moles into grams, using its molar mass:
2.3 mol Li₃PO₄ * 115.79 g/mol = 266.3 g

How many moles are in a 12.0 g sample of NiC12
Answer:
0.17 moles
Explanation:
In the elements of the periodic table, the atomic mass = molar mass. Ex: Atomic mass of Carbon is 12.01 amu which means molar mass of Carbon is also 12.01g/mol.
In order to find the # of moles in a 12 g sample of NiC-12, we will need to multiply the number of each atom by its molar mass and then add the masses of both Nickel and C-12 found in the periodic table:
Molar Mass of Ni (Nickel): 58.69 g/molMolar Mass of C (Carbon): 12.01 g/molSince there's just one atom of both Carbon and Nickel, we just add up the masses to find the molar mass of the whole compound of NiC-12.
58.69 g/mol of Nickel + 12.01 g/mol of Carbon = 70.7 g/mol of NiC-12There's 12g of NiC-12, which is less than the molar mass of NiC-12, so the number of moles should be less than 1. In order to find the # of moles in NiC-12, we need to do some dimensional analysis:
12g NiC-12 (1 mol of NiC-12/70.7g NiC-12) = 0.17 mol of NiC-12The grams cancel, leaving us with moles of NiC-12, so the answer is 0.17 moles of NiC-12 in a 12 g sample.P.S. C-12 or C12 just means that the Carbon atom has an atomic mass of 12amu and a molar mass of 12g/mol, or just regular carbon.

It’s the only one that makes sense if you read the question
if the pressure, volume, and tempature of a gas are known which can most likely be found by using the ideal gas law
• the molar amount of the gas
•the partial pressure of the gas
•the stand temperature
•the molar mass
Answer:
• The molar amount of the gas
Explanation:
Hello!
In this case, according to the ideal gas law:
[tex]PV=nRT[/tex]
Whereas P stands for pressure, V for volume, n for the molar amount of the gas, R for the universal gas constant and T for the temperature, we can see that as pressure, volume and temperature are given, we can compute the molar amount of the gas as shown below:
[tex]n=\frac{PV}{RT}[/tex]
Since R is a constant always.
