The actual molarity of the NaCl solution is lower than
0.5236 M. The student first attempted to dissolve the NaCl in
a separate vessel, which is the correct procedure; however, he did not
dissolve all of the NaCl, so the entire quantity of solute was
not transferred to the volumetric flask. Since the number of
moles transferred was less than anticipated, the actual molarity
of the solution is lower than expected.
