Determine the mass in grams needed to make 1 L Of solution how many g of KCl is needed to make an aqueous solution which has a .15 M concentration of potassium ion? Determine the mass in grams needed to make 1 L Of solution

Explanation / Answer

Ans. Molar mass of KCl = 74.55 g/mol

Molarity = x / (molar mass * vol.)

x = 0.15 * 74.55 * 1 = 11.18 g

11.18 g of KCl is required
