Problem 1. Calculate the percent concentration (the percentage) of the solution obtained by mixing 29.1 g of Ca(OH)2 and 170.9 g of water. Problem 2. 1. How many grams of Ca(OH)2 are needed for preparing 150 g of a 14.55 % solution? 2. What is the volume of 150 g of this solution if the density at room temperature is 1.0895 g/ml? 3. What is the molarity of this solution? 4. What is the normality of this solution? 5. What is the molality of this solution? Compare the molality and molarity of the solution. Problem 3. What is the molality of a solution prepared from 9.8 g of H2SO4 and 500 ml of water? (The density of water at 20C is 0.9982 g/ml)
