Concentrated aqueous sulphuric acid is 98% h2so4 and has a density of 1.80 gm/L what is the molarity of solution? Plz don't send any link as I have checked them all Answrr of this ques. is 10M but I don't know the solution. Plz help...........

To find Molarity, we need moles and volume in litres.

Moles of H2SO4:  moles=mass/ molar mass...molar mass= (2+32+64)=98

mass of the H2SO4:  since density is 1.8gmL that means 1800g in every liter.

and we know that this 98% H2SO4, hence its mass in 1liter would be (98/100 x 1800)=1764
therefore the moles= 1764/98  =18

Molarity of a solution= moles/volume(in litres).....the volume we used was a liter.

hence molarity will be   18moles/1litre= 18moles/litre
                                         =18M
