Answer to Question #68351 in Physical Chemistry for Jacob mcalughlin

Question

calculate the molarities of the solutions prepared by dissolving the following solutes in sufficient water to produce the given volumes of solution.
16.7 g CaCl^2 in 400.0 mL solution

Answer 1

Answer:
n(CaCl2) = m(CaCl2) / M(CaCl2) = 16.7 / 111 = 0.15
c(CaCl¬2) = n(CaCl2) / V(solution) = 0.15 / 0.4 = 0.375 M
