Whats the mass concentration of H2SO4 in a solution with percent mass 36% and density 1.84g/cm3

W(H2SO4)=36%?
density(H2SO4)=1.84g/cm3
MassConcentration=?

Exactly what do you mean by mass concn. You have 36% which is mass concn to me.
If you want molarity it is done this way.
1.84 g/cc x 1000 cc x 0.36 x (1 mol/molar mass) = moles/L = M.
