Best answer
The correct choice is (a) 22.4 liters

The explanation: Every one Mole of gas at STP consists of 22.4 liters of volume, that is at 0° Celsius of temperature and one-atmosphere pressure or 76 mm of Mercury pressure. Also, note that one mole of a gas is the amount of gas in weight divided by the molecular weight of the gas.
