I am trying to use Excel to help me to calculate the molar mass of chemical compounds. I would like it so I can basically type =SUM(Hydrogen*2,Oxygen) and get the molar mass of 18.02.
I have the whole periodic table in Excel. The Elements are in Column A and their Molar Masses are in Column B.
How would I get this to work?
 

Excel Facts

Round to nearest half hour?
Use =MROUND(A2,"0:30") to round to nearest half hour. Use =CEILING(A2,"0:30") to round to next half hour.
Highlight your elements and molar masses, but not any heading columns.

Press CTRL+SHIFT+F3

It should pop up with only "Left" checked.

Click ok, and have fun.
