Homework Help: CHEMISTRY

Posted by Casey on Saturday, July 10, 2010 at 5:25pm.

How many grams of CH4 are required to produce 43 g of Cu according to the following equation: 4CuO + CH4 --> CO2 + 2H20 + 4Cu?

I already tried to work the problem myself, and I may have gotten this right, but I do not have an answer key to compare to.

#gCH4 = (43gCu) x (1 mol Cu/63.55gCu) x (16.05gCH4/1 mol CH4) x (1 mol CH4/ 4 mol Cu) =

=2.71 mols x 16.05 = 43.57g of CH4.

Is this correct? If not, can someone please show me how to do this correctly. I could have figured it out but I do not have an answer key to work with.
