A 6.00 M H2SO4 solution has d = 1.34 g/mL. What is the mass percent of H2SO4 in this solution?
Choose one answer.
a. 56.1
b. 43.9
c. 37.0
d. 58.8
When we calculated yesterday the answer was not B. 43.9....I got it wrong and don't know why if the math was correct and I followed the steps you showed me.

I think the answer is 43.9% H2SO4. I looked this up in a VERY OLD text book, back in the days when they printed such stuff in texts (you can't find it these days in texts) and they show %H2SO4 = 43.74% for a density of 1.340 g/mL. (They don't show that as 6.00 M but we could calculate it and find it is 5.97 M.)
