At 300 K , a sample of 3 . 0 g of gas A occupies the same volume as 0 . 2 g of hydrogen at 200 K at the same pressure. The molar mass of gas A is g mol - 1 . (nearest integer) Assume that the behaviour of gases as ideal. (Given: The molar mass of hydrogen H 2 gas is 2 . 0 g mol - 1 .)

Correct answer

0

Step-by-step solution

PV = nRT V = nRT P V H 2 = V A   ( Given ) nRT P A = nRT P H 2 3 × 300 M A = 0 .2 2 × 200 Hence, the molar mass of A, M A = 45 g
