32 g of oxygen and 3.0 g of hydrogen are mixed and kept in a vessel at 760 mm pressure and `0^(@)C`. The total volume occupied by the mixture will be nearly

Options

A. 22.4 litres
B. 33.6 litres
C. 448 litres
D. 44800 ml

Answer

D

Explanation

n of `O_(2) =(16)/(32) =(1)/(2)`, n of `H_(2) = (3)/(2)`
Total no. of moles `=- (3)/(2) +(1)/(2) =2`
`V= (nRT)/(P) = (2xx.082 xx 273)/(1) = 44.8 lit = 44800 ml`
