Determine how many moles are used.

In the laboratory you are instructed to add 2 drops of 0.15 M AlCl3 to 2 drops of 0.15 M NaOH. If twenty drops makes one milliliter, determine how many moles of AlCl3 are used. How many moles of NaOH are used?

Solution Preview

If you have 2 drops and 20 drops is a mL...

2 drops(1 mL/20 drops) = 0.10 mL = 0.00010 L

If you have 0.15 M AlCl3, then...

moles of AlCl3 = (0.00010 L)(0.15 mol/L) = ...
