A solution is made by taking 54.62 grams of K₂CrO₄ in enough water to make 250.0 mL of solution. The molarity of the solution is therefore

Question

Quizplus · Accepted Answer

To find the molarity, divide the number of moles of K₂CrO₄ by the volume of the solution in liters. The molar mass of K₂CrO₄ is approximately 194.19 g/mol. Thus, 54.62 g corresponds to 0.2812 moles. Dividing by 0.250 L gives a molarity of 1.125 M.
