Answer:

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?
