1.

The solubility of H_2O_2 is 48 gm in 500 ml calculate volume strength and %w/v.

Answer»

34.62,19.2
31.62,19.2
31.62,9.6
30.2,9.6

Solution :MOLARITY=`"Weight of solute gm"/"MOLECULAR X Volume of solution"`
`=48/(34xx0.5)=2.82 M H_2O_2`
%w/v = `(Mxx34)/10 = (2.82xx34)/10`=9.6
V=M x 11.2 = 2.82 x 11.2 = 31.58
