If you have 1 litre of #H_2SO_4# at 96% w/w, what is the volume of water it contains?.

Question

Do you have to know the mass to work this out?

Thanks.

The volume of water is #=73.4cm^3#

From the tables, the density of #96%# is #d=1.8355gcm^-3# at #20^@C#

Therefore,

#1Liter# of #H_2SO_4# at #96%# has a mass of #=1.8355kg#

The mass of pure sulfuric acid in this liter is

#m_(H_2SO_4)=96/100*1.8355=1.7621kg#

The mass of water is

#m_(H_2O)=1.8355-1.7621=0.0734kg#

Assuming the density of water is #=1gmcm^-3#

The volume of water is #=73.4cm^3#
