Type your numerical answers in the box provided in three significant figures (e.g., 0.123). Do not report your answer in scientific notation. No need for units. If Canvas drops your last zero digit/s, it is OKAY. (e.g. 1.20 to 1.2). Consider a solution of 0.00500 M HBr for numbers 22-24. Determine the following: 22. equilibrium molar concentration of H;O' = M 23. equilibrium molar concentration of Br = M | 24. pH =
