How to Calculate Molar Mass
1. Count How many atoms you have of each element.
2. Find the atomic mass of each element and multiply it by their number of atoms.
3. Add up all the masses.
9
Example: Find the molar mass of Magnesium Nitrate Mg(NO3)2!
Count Number of atoms.
Find atomic mass from periodic table and multiply it by number of atoms. (use Dynamic Periodic Table)
Add up all of the masses.
10
Example: Find the molar mass of Glucose C6H12O6!
Count Number of atoms.
Find atomic mass from periodic table and multiply it by number of atoms. (use Dynamic Periodic Table)
