How to find gram molecular mass

Use the molecular formula to calculate mass.

1) Look up the relative atomic mass of each element in the formula.

2) Multiply the subscript after each element symbol (the number of atoms) by that element's atomic mass. If there is no subscript, it means there is only one atom of that element in the molecule.

3) Add all of the values together to find the gram molecular mass.

Explanation:

water and alcohols have similar properties because water molecules contain hydroxyl groups that can form hydrogen bonds with other water molecules and with alcohol molecules, and likewise alcohol molecules can form hydrogen bonds with other alcohol molecules as well as with water.
