Hexane is a hydrocarbon (a molecule containing only carbon and hydrogen) with a molecular weight of 86.18 g/mol,

a density of 0.660 g/mL, and a boiling point of 69C.

Pentanol is an alcohol (a hydrocarbon with a "OH" group attached to one of its carbons) with a molecular weight of
88.15 g/mol, a density of 0.814 g/mL, and a boiling point of 137C.

Calculate the volumes if 2.50 moles of each chemical is present.

2.5 moles of each implies

86.18g/mole*2.5moles=215.5g
215.5 g / .660 g/mL = 326.4 mL

88.15 g/mole * 2.5moles=220.4g
220.4 g / .814 g/mL = 270.7mL
