Calculate the molar mass of potassium hydroxide (KOH). How many atoms
would we find in a 100 mL solution of 1 µM KOH?

  • Chemistry (mole question) -

    0.1 L * 1µ mole/L = 10^-7 moles = 6.02 * 10^16 molecules.

    If you want atoms of solute, then that would be 3 times as many.
    If you also want to include the H2O, then you need to add the 100ml of H2O to the mix.
