A) A student performed the freezing point depression experiment according to directions but mistakenly recorded the mass of lauric acid as 8.300 g instead of 8.003 g. The calculated molar mass of the unknown acid will be ___________ than the true value, because the mass of lauric acid appears in the denominator of the unknown acid's molecular weight determination


A. less
B. greater

(B) therefore, if it was mistakenly recorded too high, it would ___________ the calculated moles of the solute.


A. increase
B. decrease

    the unknown should be less then its true value and the calculated moles would be increased i believe

    yup he's right.
