Answer 1 and 2. Kindly show complete solution. Thank you.
Task 1: Determine the concentration of a solution Direction: Solve the following problems, complete with solutions. Place a box on your final answer. Use 2 decimal places for the final answer. 1. A 100 mL solution contains 5.7g MgCl₂ (MM = 94 g/mol). The density of the solution is 1.03 g/mL. Express the concentration in: a. % by mass b. Molarity 2. A 68.8 g H₂SO4 (MM = 98 g/mol) is added to H₂O to make a 500 mL solution. If the density of the solution is 1.2 g/mL, calculate the molality.
