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 4.50 moles of each chemical is present.
Hexane: ____mL

Pentanol: _____mL

  • Chemistry - ,

    First compute the masses using the molecular weight (which are given) and the number of moles (4.5).

    Then divide by the density to get the volume.

    Do this separately for each compound.
