Determine the percentage composition of your compound. Percentages can be entered as decimals or percentages ie. For example the molecular formula of glucose is C 6 H 12 O 6 but the empirical formula is CH 2 O.
50 can be entered as50 or 50 To determine the molecular formula enter the appropriate value for the molar mass.
This is because we can divide each number in C 6 H 12 O 6 by 6 to make a simpler whole number ratio. I have the shortest method ever to do it although its no. That will give you the range for 68 of the data values. You do this conversion by assuming that you have 100 g of your compound.
