How do you calculate mass at STP?

Sagot :

The formula D= M/V is used at STP where,

M is equal to the molar mass and,

V is molar volume of a gas (22.4 liter/mole).

At Standard Temperature and Pressure (STP), 1 mole of any gas will occupy a volume of 22.4 L.

The Ideal Gas Law, along with a balanced chemical equation, can be used to solve for the amount, either in volume or mass, of gas consumed or produced in a chemical reaction.

The molar mass of a gas can be derived from the ideal gas law, PV=nRT , by using the definition of molar mass to replace n , the number of moles.
