Question

What is the molarity of H₂SO₄ solution, that has a density 1.84 g/cc ar 35°C and contains 98% by weight?

(a) 18.4 M

(b) 18 M

(c) 4.18 M

(d) 8.14 M

Answer 1

Correct option (a) 18.4 M

Explanation :

We know that 98% H₂SO₄ by weight means 98 g of H₂SO₄ is present in 100 g of solution in water.

Therefore, its weight is 98 and moles of H₂SO⁴
