What volume of H2so4 Solution Cspecific gravity=-1.28 and strength =24.7% by mass) will be required to react completely with 125g ZnC032?

The volume = 309.04 ml

Further explanation

Given

Specific gravity=-1.28 and strength =24.7% by mass of H₂SO₄

mass 125g of ZnC0₃

Required

The volume of H₂SO₄ Solution

Solution

Reaction

ZnCO₃ + H₂SO₄ → ZnSO₄ + CO₂ + H₂O

mol of ZnCO₃(MW=125.4 g/mol) :

From equation, mol ZnCO₃ : H₂SO₄= 1 : 1 so mol H₂SO₄=0.997

mass of H₂SO₄ (MW=98 g/mol) :

mass of solution :

Volume of solution :(density of solution=1.28 g/ml for the reference substance is water(density=1 g/ml)

The answer for this question is d. none of these
