Assume that a student performs a pH titration to determine the molar mass of an unknown weak acid. The student uses poor lab practice by writing down the mass of his unknown sample on a piece of paper towel and then copies down the value incorrectly onto his data page. The actual mass of the sample was 0.2145g. He mistakenly wrote down 0.1245g, but otherwise performed the experiment correctly. What effect, if any, will this on the molar mass of the unknown acid (too high, too low, or no effect)? Explanin why.
