gen chem: molarity : help!

[lilietta2000]

can somebody help me with problem, please?


What is the molarity of an aqueous H2SO4 solution which has a specific gravity of 1.75 and is 39.2% H2SO4 by mass?

Ok, if I am not wrong the specific gravity is used as Density will be in this problem...So,
0.392x (1mol/98g)x (1.75g/ml)x (1000ml/1L) = 7M

Correct me if I am wrong... Not so sure about the specific gravity, have done similar problems with density.

yeah you use the specific gravity as the density

Thanks for confirming...!!

specific gravity is the same thing as relative density
