Question

I am somewhat lost on step four.

Step 4: Multiply the mole ratio by the smallest whole number that changes it into a whole number ratio to find the atom ratio of elements in the sample. element mass % mass moles mole ratio Step 4: atom ratio carbon 17.9% 17.9 g 1.49 mol 1.00 2 x 1.00 = 2.00~2 hydrogen 2.26% 2.26 g 2.24 mol 1.50 2 x 1.50 = 3.00~3 chlorine 79.7% 79.7 g 2.25 mol 1.51 2 x 1.51=3.02 23
