4.10 L of a 6.00 M NaOH solution

Answer 1

If I am understanding your question are you trying to find the amount of moles that need to be added of NaOH. If so, you would have to use the Molarity Equation (Molarity (M) = moles of solute / Volume of solution (L))

-Molarity = 6 M NaOH, Volume = 4.10 L NaOH

-M = moles/L can be rewritten as moles = M x L

-Moles = 6 M NaOH x 4.10 L NaOH = 24.6 moles of NaOH
