Confromation for Empirical Formula Question (not asking you to do it for me) watch

1. So basically the question is that there is 2.3 grams of a compound , it contains 1.2g of carbon , 0.3g of hydrogen and 0.8 of oxygen, I found the number of moles in each and ended up with 0.1 , 0.3 , 0.65 , now I am confused where i go next to find the formula. Is it CH3O7
2. Hi there!

You've basically got it - just check your calculation for the number of moles of oxygen (it's a bit high - its 0.8/16).

If you calculate this, then I think you've got the idea - divide all the values by the smallest number.

Just a tip - when you work out the formula at the end, if the value is 6.5, you would have to double all of your numbers to get whole numbers as you can't disregard 0.5 of the atoms (also, in this case the there should be more H atoms that C and O - again, check O molar calculation!)

Good Luck
