For the reaction 2H 2 +O 2 2H 2 O calculate the percent yield if 860. of water is produced when 100. g of hydrogen react with an excess of oxygen?

The percent yield : 95%

Given

Reaction

2H₂+O₂ ⇒2H₂O

Required

The percent yield

Solution

mol of Hydrogen(as a limiting reactant) :

mol H₂O based on H₂ , and from equation mol ratio H₂:H₂O=2 : 2, so mol H₂O = 50

Mass of water(theoretical yield) :

quartz

explanation:

i believe it is c.) 1575 j.
