7.0 mL of 3.0 M NaOH are diluted with water to a volume of 400 mL. (a) Determine the molarity of the resulting solution. How many moles of NaOH there are in 7.0 mL of 3.0 M NaOH? Hint: Use Eq. 1 and make sure the volume is in liters: MA = mol A / soln (L) OR mol A = MA x V ___________ moles (b) The total number of moles of NaOH is not changed on dilution. The molarity after dilution can therefore be found by MA = mol A / soln (L) OR mol A = MA x V using the final volume of the solution. Calculate that molarity.
