Homework Help: Chemistry pls help

Posted by tricia on Wednesday, December 3, 2008 at 8:23pm.

I have a chemistry question
Please advise how do I prepare 1L of 75% H2SO4 from concentrated H2SO4 (98% of density 1.84g/ml)? Do you have an equation which i can use? Someone gave me the following equation but I do not understand it.

Vx1.84x0.98={(1000-V)+ 1.84V}0.75

where V= volume of conc H2S04 needed to prepare 1L of 75% H2SO4.

Thanks for your help.
