86.178 "g"/"mol"86.178gmol

Explanation:

Hexane, whose chemical formula is "C"_6"H"_14C6H14 has a molar mass of 86.178 "g"/"mol"86.178gmol

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

Hexane also has 1414 Hydrogen atoms which each atom having a mass of 1.008 "g"/"mol"1.008gmol

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