@zleap Molar, or more specifically Molarity would just be a different way of measuring concentration.
@zleap A molarity of 1 would be 1 mole of atoms of sulfuric acid dissolved in 1 liter of water
So if H2SO4 has a molar mass of 98.07848 g/mol (it does),
Then 1 molarity sulfuric acid is a 9.8% solution.. so 98% would be 10 molarity.
