Lesson 15:

Today we learned a lot more about Molarity and solutions ect. Molar mass allows you to convert between grams and moles. The amount in grams of solid that is needed to create solutions of specific molarities can be calculated using the molar mass of the solid. Also, the mass of solid dissolved In a solution can be found if the concentration and volume are known. By using the chart Mrs. McDowell always yells at us to do ;) is very helpful when figuring out mass. Mass = Moles times Molar Mass, also, to find Moles, Moles = Molarity times Volume. Lastly, to find Molarity it is M=moles over Liters. Homework below!
