Question

3.49g of ammonia at STP occupies a volume of 4.48 $${ dm }^{ 3 }$$ calculate the molar mass of ammonia. 


A
13.25 g/mol
loader
B
14.59 g/mol

C
17.45 g/mol
loader
D
None of these

Solution

The correct option is C 17.45 $$g/mol$$
Volume = 4.48 $$dm^3$$ = 4.48 L
Gram Molecular Mass = 22.4 L at STP
So,
4.48 L of ammonia gas weighs = 3.49 g
22.4 L of ammonia weighs = $$\frac{22.4 \times 3.49}{4.48}$$
= 17. 45 g / mol
