Maybe I am doing something horribly wrong here, but these numbers just make absolutely no sense to me. We are given solubility values which will subsequently be used for Ksp calculations. I was given hydrogen bromide and 5 solubility values (given in g/100g H2O) Since 1g = 1mL basically we were given g/100mL. To calculate Ksp we need mol/L so I converted. One value we were given was 193.8g/100mL So first I converted to g/L by multiplying by 10. 1938g/L. Next I divided by the molar mass to get mol/L (80.91g/mol). This value ends up being 23.95mol/L which is a ridiculously high number. Did I do something wrong???
