First, it is not possible to get 100% H2SO4; some water will be absorbed into the acid. The amount will depend on the humidity, so there is no single answer. However, on a hypothetical basis, assuming you have 100% H2SO4 (which is a liquid), you would get the molecular mass of H2SO4 which is 98 gm/mole. From the density of H2SO4 1.84 gm/cm^3, one liter would have a mass of 1.84*10^3 gm. Divide that by 98 to get 18.8M

molarity is defined as number of moles present per litre of solution
so the number of moles in the solution or normality should be known or some other data should be given to answer this question
