Answer :
Final answer:
The molar mass of the unknown gas is 0.5 g/mol.
Explanation:
To calculate the molar mass of the unknown gas, we can use the fact that the volume of hydrogen (250 cm³) refuses four times as rapidly as the volume of the unknown gas (also 250 cm³). Since the volume is the same, the ratio of the molar masses of the gases is equal to the inverse ratio of their rates of effusion. Therefore, the molar mass of the unknown gas can be calculated by dividing the molar mass of hydrogen (2 g/mol) by 4. The molar mass of the unknown gas is 0.5 g/mol. None of the given answer choices match this value, so none of them are correct.
