Show all your work and use the correct number of significant figures and units. 1. A potassium nitrate solution is made by mixing 8.52 g of potassium nitrate with 120.0 mL of water. Use the molar mass of KNO3 given below if necessary. Molar mass of KNO3 = 101.10 g/mol a. Determine the number of moles of potassium nitrate used to make the solution. Show your work. (10 points) b. Determine the mass (in kg) of solvent used to make the solution. Assume that the density of water is 1.000 g Show your work. (10 points)​
