When carbon is burned in air, it reacts with oxygen to form carbon dioxide. When 16.8g of carbon were burned in the presence of 59.9g of oxygen, 15.1g of oxygen remained unreacted. What mass of carbon dioxide was produced?

options?

anonymous · Answer

C is the limiting reactant (because all of it burned) so CO2 is based on the amount of carbon that burned.
16.8g C x (1 mol C / 12.0 g C) x (1 mol CO2 / 1 mol C) x (44.0g CO2 / 1 mol CO2) = 61.6 grams and that does have 3 sig figs

I'm a bit rusty so you should probably have someone else check it...

mass of carbon dioxide  produced: 58.5g....

Work please? Could I see where I went wrong? 
I was under the impression that 12g of C gets you 44g of CO2 so I got the same answer using ratios

so is the anwer 61.6
