1. A graduate measured out a 100. mL hard water sample and titrated it with 37.6 mL of 0.0100 M EDTA solution for a total hardness endpoint, and 29.3 mL of 0.0100 M EDTA solution for a calcium endpoint. Calculate the molarity with respect to magnesium and calcium. Please calculate the mg/L Ca and mg/L Mg of the unknown
2. Explain the different conductivity values expected from both a rain water sample and an oil field brine water sample
