Answer

CH4, CO2, and NH3 at STP are 22.37 L, 22.26 L, and 22.06 L, respectively rather than the ideal molar volume of 22.41 L.

Work Step by Step

As molecules grow larger and become more polar, inter-molecular forces are likely to result. Inter-molecular forces cause the molecules in these gases to get closer to each other, leading to an increase in density and thus a decrease in molar volume.
