What is the percent yield of #O_2# if 10.2 g of #O_2# is produced from the decomposition of 17.0 g of #H_2O#?
The percent yield can be calculated by:
The actual yield of oxygen is given and it is
We will need to find the theoretical yield.
The decomposition reaction of water can be written as:
To find the theoretical yield of oxygen we will use dimensional analysis:
Thus, the theoretical yield is equal to
The percent yield is then:
