#86.178 "g"/"mol"#

Explanation:

Hexane, whose chemical formula is #"C"_6"H"_14# has a molar mass of #86.178 "g"/"mol"#

To find the molar mass of Hexane, we can look up the atomic masses from the Periodic Table for each element that make up Hexane and multiply each by the number of atoms in the formula and then add up everything.

Hexane, has #6# Carbon atoms with one Carbon atom having an atomic mass of #12.011"g"/"mol"# (Some periodic tables may round this differently but it's more or less the same)

Hexane also has #14# Hydrogen atoms which each atom having a mass of #1.008 "g"/"mol"#

#:." Molar Mass of Hexane" = (6*12.011)+(14*1.008) = 86.178 "g"/"mol" #
