Chemistry (mole question)

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