Question

How many moles of water will be produced from the complete combustion of 29.2 moles of ethane according to the following reaction?

2 C2H6 + 7 O2 → 4 CO2 + 6 H2O

Answer 1

Easy....Use Stoichiometry
\[2 mol C _{2}H _{6}\rightarrow 6 mol H _{2}O\]
\[29.2 mol C _{2}H _{6}\rightarrow 3 X 29.2 mol H _{2}O\]

Answer 2

So, would that be:
29.2 mol C2H6*(6 mol H2O/2 mol C2H6)
=87.6 ?

Answer 3

My textbook doesn't explain things well and I normally have work during my class so, if you could explain anything it would be extremely helpful.

Answer 4

Yup...Thats the way mate........
