The molarity (M) of a solution is calculated using the formula M = moles of solute / liters of solution. First, we need to calculate the molar mass of CaCl2. The molar mass of Ca (Calcium) is approximately 40.08 g/mol, Cl (Chlorine) is approximately 35.45 g/mol, so the molar mass of CaCl2 is 40.08 + (2 * 35.45) = 111.08 g/mol. Next, we convert 34 grams of CaCl2 to moles: 34 g / 111.08 g/mol = 0.306 moles. Then, we convert 150 ml to liters (since molarity is moles/liter): 150 ml = 0.15 liters. Finally, we calculate the molarity: 0.306 moles / 0.15 liters = 2.04 M.
