At "STP", 1 mole of an Ideal Gas occupies 22.4*dm^3 or 22.4*L

Explanation:

(And of course this definition differs across curricula, and across countries...........)

So "mass of ammonia"=(35.4*L)/(22.4*L*mol^-1)xx17.03*g*mol^-1

~=27*g.

I have assumed Ideal Gas behaviour here. Given that we assess the behaviour of ammonia gas, is this a reasonable assumption?
