Mass of solute in 100ml of solution = 90 g of H₂SO₄

 

 

Moles = Mass of solute in 100ml in solution   = 90 = 0.9183

                              Molar mass                             98

 

Volume = mass X density

 

Wt of 100ml of solution = 100 X 1.8 = 180 g

 

Solution = solvent + solute

 

       180= x  + 90

         x = 180 -90 = 90 g

 

Molarity = No. of moles of solute  =  0.9183  =  0.0102 X 1000 = 10.2 M

                 A volume of solution             90
