LAB 8 -Molarity, Percent Solution and Conductivity **Print this worksheet, and complete it by hand and in pencil. Then, use the Camscanner app (there are instructions on how to use Camscanner in the Practice and Orientation Module) to create a pdf file that will be submitted through Blackboard. If printing is not an option for you, you may use blank paper to complete this worksheet. Write "Lab 8 " on top of each page and number the questions as you answer them. Part I: Molarity 1. In Module 8, we are learning how to calculate the molarity of solutions. Using your knowledge of molarity, solve the following problems: ( 5pts ) a) 12.5 moles of NaCl were dissolved to make 0.5L of solution. What is this solution's molarity? b) 1.45 moles of Na(OH)2? were used to make 1.5L of solution. What is this solution's molarity? c) 50g of H2?CO3? were used to make 2L of solution. What is this solution's molarity? (Hint: convert mass to moles first.)
