Question

3.2 g of oxygen (at. Wt. = 16) and 0.2 g of hydrogen (at. Wt. = 1) are placed in a 1.12 litre flask at 00c, the total pressure of the gas mixture will be a) 1 atm b) 4 atm c) 2 atm d) 2 atm

Answer 1

Explanation:

Mole of oxygen is 1/2 as 16/32 and mole of hydrogen is 3/2 .

Therefore total moles is 1/2+3/2=2.

Using PV=nRT..V=( 2*0.0821*273.15)/1=44.851 lit
