Which law is used to calculate the number of moles in a contained gas?
Wiki User
∙ 14y ago
in normal conditions (0 degrees Celsius and pressure of 1atm) 1 mole of any gas has a volume of 22,4 litres.
so use the formula
n=V/Vm
n - amount of moles
V - volume of gas
Vm =22,4l/mol

∙ 14y agoThe Ideal Gas Law is used:
PV = nRT
Where P = pressure
V = volume of the container
n= number of moles
R = gas constant (given as 8.314 m3 Pa/K mol)
T = temperature
The value of the gas constant can be easily adjusted to fit with any units, the above is using the SI units in all cases.

∙ 14y agoUse the ideal gas law. PV = nRT P = Pressure
V = Volume
n = Mols of Gas
R = Gas Law Constant - look up in a book
T = Temperature
Wiki User
∙ 14y agoThe ideal gas law: PV=nRT Where:
P = pressure
V = volume
n = moles
R = the gas constant
T = temperature

Can you calculate the number of moles of magnesium used grams permol?
Yes
How is stoichiometry used to calculate amount of product from amount of reactant?
The coefficients give the ratio of moles reactant to moles product.
How is stoichiometry used to calculate the amount of product produced?
Stoichiometry relates moles of reactant to moles of product, so if you have the amount of reactant in the equation, you can calculate the amount of product produced.
How is stoichiometry used to calculate the mass of a substance?
Unit conversion factors are used to convert between units of grams and moles.
How is the number of moles of an element determined froma known mass?
the molar mass is used as a conversion factor to convert grams to moles
Can you calculate the number of moles of magnesium used grams permol?
Yes
How can you use moles to solve problems?
moles can be used to calculate gmv(gram molecular weight)
How is stoichiometry used to calculate amount of product from amount of reactant?
The coefficients give the ratio of moles reactant to moles product.
What is the molarity a measure of?
Molarity (M) indicates the number of moles of solute per liter of solution (moles/Liter) and is one of the most common units used to measure the concentration of a solution. Molarity can be used to calculate the volume of solvent or the amount of solute.
How is stoichiometry used to calculate the amount of product produced?
Stoichiometry relates moles of reactant to moles of product, so if you have the amount of reactant in the equation, you can calculate the amount of product produced.
How is stoichiometry used to calculate the mass of substance?
Unit conversion factors are used to convert between units of grams and moles.

How do go from moles to ions?
To go from moles of an ionic compound to the number of ions you must multiply your number of moles by Avogadro's number (Avogaro's number is approximately 6.02 • 10^23). So lets say you have 2 moles of a sulfate ion you would do (2moles)(6.02 • 10^23 ions/mole) = 1.20 • 10^24 Avogadro's Number is used to convert any substance between moles and # of atoms/molecules/ions
