A student prepares a solution of carbonate-free NaOH. Upon drama a rough titration, the student finds the concentration to be 0.0673 M instead of 0.1000 M. presuming that the volume of the solution is 950.0mL, explain how many grams of sodium hydroxide should be added to the solution to produce a concentration as close as possible the desired 0.1000 M? Presume that the sodium hydroxide is carbonate-free.
