Question

What is the molarity of 28.9g of calcium chloride dissolved in water to make 0.78L of solution​

Answer 1

.334 M

Step-by-step explanation:

Ca Cl2 is calcium chloride

Ca = 40.078 gm/mole

Cl = 35.45 gm/ mole

40 . 078 + 2 * 35.45 = 110.978 gm/mole for Ca Cl2

28.9 gm / 110.978 gm/mole = .260 moles CaCl2

.260 moles/ .78 liter = .334 M
