Answer: B. 2 moles of gas occupy 22.4L at STP

Explanation:

At STP, meaning; at a temperature equal to 273.15 K and a pressure equal to 1.00 atm or 101.3kPa, one mole of any gas will have a volume of 22.4 L.

So, if 1 mole occupies a volume of 22.7 L, 2 moles will occupy a volume twice as big, which is 45.4L and not 22.4L.
