4 g of O_2 and 2g of H_2 are confined in a vessel of capacity 1 litre

1.	4 g of O_2 and 2g of H_2 are confined in a vessel of capacity 1 litre at 0^@C. Calculate the partial pressure of each gas, and
Answer» Solution :CALCULATION of partial pressures : Volume of vessel = 1 L, `T = 0^@C = 273 K` `:. "" PV = nRT " or " p = (nRT)/V` `:.` Partial pressure of oxygen `Po_2=(nRT)/V =( 0.125 xx 0.0821 xx 273)/1 = 2.80` atm Similarly, partial pressure of hydrogen `P_(H_2)= (nRT)/V= (1xx0.0821 xx 273)/1= 22.4` atm
