We’re being asked to calculate the percent yield of H2O. The balanced chemical equation is:
2 H2 + O2 → 2 H2O
Recall that percent yield is given by:
In the reaction of 1.00 mole of O2 with 2.00 mole of H2, 2H2 + O2→ 2H2O
If 30.0g of H2O is formed, what is the percent yield?
a) 100%
b) 88.9%
c) 50.0%
d) 167%
e) 83.3%
