Molarity calculations have already been presented. If you need a refresher, go to Schoology Material section and look in 2024-2025 Chem328 Solution Mole Calculation folder (notes, example of work, etc). In this folder is the direct link to the You Tube video on Molarity calculations (this bypasses Edpuzzle).
The following problem will refresh your memory on how to calculate a specific type of Molarity calculations.
1a) Give the symbol and charge of each ion and then the chemical formula for Barium hydroxide.
1b) How many grams of Barium hydroxide do you need dissolve so that you can have a 450.ml of a 0.250M Barium hydroxide solution? (Answer 19.2g)
