Calculate the pH of the solutions formed by dissolving 1.0g of each of the following substances in 500mL of solution:
a.) HBr
b.) Na2O
c.) SrO
My professor did not cover these examples in class. I believe I need to setup a chemical equation and use stoichiometry, but confused on where to start. Any help is appreciated.
