Question

5.6 litres of gas at NTP are found to have a mass of 11g The molecular mass of the gas is

Answer 1

Answer for this question is 44g

Answer 2

Answer:44u

Explanation:

1 mole of a gas occupies 22.4 litres of volume at STP.

5.6 litres indicates 0.25 moles of the gas.

Given that,

0.25 moles of the gas weighs 11 grams

so, 1mole of the gas will weigh 11 x 4 = 44 grams

Hence the molecular weight of the gas is 44 grams
