2 g of a carbon compound is burnt in excess oxygen. 4.77g of CO2 is produced. What percentage (to the nearest 1%) of carbon is in the original compound?
What is the meaning of the phrase “is in the original compound”? Is the meaning what is the percentage yield? what is the reaction equation? how to solve this ??
Hi, I think the original compound means the 2g of unknown carbon compound.
I’m not exactly sure with the balanced equation, but I got the percentage by
(CO2 moles)/(Unknown carbon compound moles) * 100%.
Thank you for answering! how did you get to 0.108 without a calculator?
I erased the process cause it looked messy but it looked something like this.
I rounded up to 3 significant points
