Homework Help: Chemistry

Posted by Tiffany on Sunday, February 28, 2010 at 5:56pm.

CS2(g) + O2(g) CO2(g) + SO2(g)
(a) Consider the unbalanced equation above. What is the maximum mass of SO2 that can be produced when 46.0 g of CS2 and 29.0 g O2 react?
(b) Assume the reaction in part (a) goes to completion. Calculate the mass of excess reactant.

I figured out part a and got an answer of 38.7 but I'm not sure how to do the 2nd part. Please help!
