Question

A 6.00 M H2SO4 solution has d = 1.34 g/mL. What is the mass percent of H2SO4 in this solution?

Answer 1

density = 1.34 g/mL so 1 L has a mass of what?
1.34 g/mL x 1000 mL = 1340 grams.
How much of that is H2SO4? You had 6.00 moles in that L of solution so 6.00 moles x (98 g/mole) = 588 grams.
So you have 588 g H2SO4 in 1340 g; the percent must be (588/1340)*100 = ??

You need to redo this since I estimated the molar mass of H2SO4 as 98.0 and that isn't exactly right. Check my thinking. Check my work.

Answer 2

thanks it was correct!
