I just wanted to see if I'm doing this right. Sulfuric acid is supplied as a concentrated liquid. A bottle was assayed and found to have a density of 1.84 g/mL and a purity of 97%. The molecular weight of H2SO4 is 98. What is the molarity of this solution? molarity=moles/volume moles=mass/mol.weight moles=1.84/98 moles=1.88*10^-2 assuming the volume is 1mL=0.001L, molarity=1.88*10^-2/0.001 molarity=18.80 mol/L since there is 97% purity, molarity=18.80*0.97 =18.24 mol/L Is this right? I think I'm wrong, but this was just a guess. Thanks.
