1.) If 65 mL of a 0.195 M (molarity) NaOH is diluted to a final volume of 125 mL, what is the concentration of NaOH in the diluted solution?

2.) Calculate the new molarity that results when each of the following solutions is diluted to a final total volume of 1.00 L.
a.) 415 mL of 0.145 M (molarity) HCl
b.) 10.8 mL of 12.1 M (molarity) HCl

Thanks!!

A little hint for question 1: how many mols of NaOH are present in 65 mL of a 0.195 M (molarity) NaOH ?
