Homework Help: Science, Chemistry

Posted by Tricia on Wednesday, December 3, 2008 at 2:33am.

I have been told that to prepare 1L of 70% H2SO4 from concentrated sulphuric acid (96% with density 1.84g/ml), I should use the following equation to find out the volume of conc. acid needed (Vml).

V x 1.84 x 0.96={(1000-V)+ 1.84V}0.7

i.e. V= 594ml of conc H2SO4.

Use 594ml of conc H2SO4 and top up to 1L volumetric flask with water.

Can you please explain this equation to me? Many thanks for your help.
