Calculate the total molarity of solute particles in a solution that contains 0.050 M glucose (a nonelectrolyte) and 0.200 M CaCl₂. A)0.250 M B)0.450 M C)0.650 M D)0.350 M

Question

Quizplus · Accepted Answer

- Glucose is a nonelectrolyte meaning it dissociates into one particle when dissolved in water, therefore its molarity is 0.050 M.
- CaCl2 is an electrolyte meaning it dissociates into three particles when dissolved in water (1 Ca2+ and 2 Cl-), therefore its molarity is 0.200 M x 3 = 0.600 M.
- The total molarity of solute particles in the solution is the sum of the molarities of glucose and CaCl2: 0.050 M + 0.600 M = 0.650 M.
