Question
8) The density of 2-methyl-2-butanol is 0.806 g/mL. How many mgs
represent an aliquot of 430 L? How many mmols represent an aliquot of
0.650 mL (2-methyl-2-butanol, formula weight is 88.15 g/mol)?
9) Discuss with those in your laboratory section the consequences of
incorrect sample loading, variable sample size, and rates of heating and
how these factors might lead you to obtain an incorrect value of the melting
point for your solid sample.
10) The mass of a certain volume of an unknown liquid at 25°C is 234 mg.
The mass of an equal volume of water at the same temperature is 201 mg.
Calculate the density of the unknown liquid at 25°C.
