At STP, what volume of container would be needed to hold 3.2 moles of gas?

78.4 L volume of container is required to hold 3.2 moles of gas.

Explanation:

STP is defined as the standard temperature and pressure of a gas in room temperature conditions. At STP, one mole of the gas which has Avogadro's number of molecules in it will occupy a volume of 22.4 L. So, one mole of a substance or gas will occupy a volume of 22.4 L then the volume of the container needed for  3.2 moles of gas is calculated by multiplying 22.4 L, standard volume with the moles of the gas 3.2 moles. Hence, the answer would be 78.4 L.

The most plausible answer is b, duration. the given amount of time is considered how long it last for.
