Question

At STP 1.12gm of a gas has weight 2.2gm. calculate its molecular weight.

Answer 1

Answer:

44 gm (After correcting the question)

Explanation:

First of all, your answer should be "At STP 1.12 Litre of a gas ....."

Now, coming to solution,

At STP, 1.12 Litre weighs = 2.2 gm

So, 1 Mole (22.4 Litres) will weigh = $\frac{2.2}{1.12}$ × 22.4 = 44 gm.

Hence, its molecular weight will be 44 gm.
