the density of an 18.0 solution of ammonium sulfate is 1.10g/ml. What mass of Ammonium sulfate is required to prepare 275ml of this solution

Therefore, 54.45 g of Ammonium sulphate is required

Explanation:

Molar mass of ammonium sulphate, (NH₄)₂SO₄ = 132 g/mol

Since density of solution is 1.10 g/ml, a 1 mL solution has mass = 1.10 g

275 mL solution will have a mass = 275 * 1.10 = 302.5 g

Since the solution is 18% ammonium sulphate by weight,

mass of ammonium sulphate present in 275 mL solution = 302.5 * 18/100

mass of ammonium sulphate present in 275 mL solution = 54.45 g

Therefore, 54.45 g of Ammonium sulphate is required
