Question

mass of 112 Ml of a certain gas is 0.22 g at Stp. how many molecules are there in the sample of gas ? What is the molar mass of the gas?​

Answer 1

Answer:

Hope it helps you

Explanation:

The volume occupied by 1 mole of any gas at STP is 22400 cubic cm

Number of moles of 112 cubic cm of hydrogen gas =22400112=0.005 moles

The molar mass of hydrogen gas= 2 g

Weight of hydrogen gas =0.005×2=0.01 gm

Answer 2
