15 moles of an ideal gas at STP has a volume of ____liters
S_A_V [24]

Answer:

A. 336 L

Explanation:

STP is 0 °C and 1 bar.

At STP, the molar volume of a gas is 22.71 L.

Volume = 15 mol × 22.71 L/mol

Volume = 341 L

===============

The above answer is not in your list of options.

It appears that you are using the <em>OLD</em> (pre-1982) definition of STP, at which the molar volume of a gas is 22.4 L.

Then

V = 15 mol × 22.4 L/mol = 336 L
