Question

The density of methanol, a colorless organic liquid used as a solvent is 0.7918g/mL. If the mass of a sample of methanol is 72.1g, which of the following is the correct volume?

91.0583mL or 91.1 mL ? Show work please

Answer 1

72.1g x (1 mL / 0.7918g) = 91.0583mL (91.1mL)

Technically, both answers are correct. However, because of the rule of significant figures, 91.1mL would be the correct answer for this question. In the information given in the question, the number with the least amount of significant figure is 3 (72.1g). This means your answer must als have 3 significant figures, which 91.1mL has.
