Calculation of the Number of Molecules in One Gram of Gas

To calculate the number of molecules in one gram of gas, we need to use the concept of molar mass and Avogadro's number.

1. Calculate the molar mass of the gas: - The molar mass is the mass of one mole of a substance and is expressed in grams per mole (g/mol). - To calculate the molar mass, we need to know the molecular formula of the gas. - Please provide the molecular formula of the gas in question.

Once we have the molecular formula, we can proceed with the calculation.
