Interpretation:
The mass of the gas is to be calculated at STP for a given volume of the gas.
Concept introduction:
Ideal gas equation is used to calculate mass of the gas at given temperature and pressure.
According to this law,
Where

Answer to Problem 21PP
The mass of the gas is
Explanation of Solution
Ideal gas equation helps to calculate number of moles of a gas at given temperature and pressure. According to this law,
Or
Where
Further, mass of gas
Now volume is
At STP
Pressure is
Temperature is
Gas constant is
On substituting the values in the formula:
So
Molar mass is defined as average mass of atoms present in the chemical formula. It is the sum of the atomic masses of all the atoms present in the chemical formula of any compound.
The given gas is
The formula to calculate molar mass is,
Where,
Atomic mass of carbon is
Atomic mass of oxygen is
Hence,
Therefore, mass of the gas is
The mass of the gas at STPis
