KsP calculations with solubility values

  • #1
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???

"Ridiculous?" How many moles of water per liter (liquid)? Don't let your intuition stampede you --- when the numbers look "funny," check them, check your units, check you method, look at similar problems, and move on.
