What is the mass of 22.4 litres of ammonia

1 Mole of NH3 at STP occupies volume of 22.4 l

I Mole of NH3 weighs = Molar mass =17g

So 17g of NH3 = 22.4l

Let X g   of NH3 = 11.2l

Therefore, X = (11.2 x17)/(22.4)

=8.5g

for example

there all right good

explanation:

answer

i think the answer is a) as air pressure in an area increases, the density of the gas particles in that area decreases.

hope it
