Determine the concentration of a solution prepared by diluting 25.0 mL of a stock 0.188 mol L^-1 Ca(NO₃)₂ solution to 150.0 mL.

Question

Quizplus · Accepted Answer

The concentration of the diluted solution can be calculated using the formula C1V1 = C2V2. Here, C1 = 0.188 mol L^-1, V1 = 25.0 mL, V2 = 150.0 mL. Solving for C2 gives C2 = (C1V1)/V2 = (0.188 mol L^-1 * 25.0 mL) / 150.0 mL = 0.0313 mol L^-1.
