Molarity = moles of substance

volume in liters

moles of H2SO4 = mass/ molar mass

denisty = 1.8g/ml(that is 1800g/L)

mass of H2SO4 98% of 1800= 1764g(this is mass of H2SO4 in 1L)

molar mass= 2+32+64 = 98

moles = mass/molar mass = 1764/98

= 18 moles

Therefore in !liter of H2SO4 molarity= moles/volume in liters= 18/1L

= 18M

Molarity =18M

Experts, please do not delete my answer, this answer is from the answer which I gave earlier, I have copied and pasted from MY answer itself, There's no plagiarism or copy.

You have asked the incomplete question. The question is ' Volume of acid required to make 1L of 0.1M H2SO4 is __________ .

Here's your answer:

Concentrated aqueous sulphuric acid = 98% by weight means 98 gm. H2SO4 in 100 gm.  solution.

Number of moles = 98 / 98 = 1.

Density = 1.8 g/L

Volume of the solution = Mass of solution / Density = 100 / 1.8 = 55.55 mL = 0.055L.

We know that,

               =

              18 * V1 = 0.1 * 1000

By solving, we get, V1 = 5.55 mL.
