Question

What is the volume of 1.2 moles of water vapor at STP?

Answer 1

Well, the molar volume at STP is......

Explanation:

...is specified to be `22.4*L*mol^-1`. Where `"STP"` specifies `1*atm`, and `273.15*K`.

Given `1.2*mol` of gaseous water, or indeed any gas....we gots the product......

`1.2*molxx22.4*L*mol^-1~=27*L`
