Can someone please check this for me?

Question

C4H8+5O2-->3CO2+4H2O+C Butane is a gas and .01 g of it is burned. Is .00218 g of carbon the result?
Thanks

Answer 1

I have a slight difference.
0.01 g x (1 mole C4H8/56.1 g C4H8) x (1 mole C/1 mole C4H8) x (12.01 g C/1 mole C)= 0.00214 g but we're allowed only 1 sig figure anyway which would be 0.002 g C.

Thank you very much!
