Page 147 #27 In letter a, there is a larger ratio of H:O in H 2 O than H 2 O 2 so H 2 O has the larger percentage of hydrogen. In letter b, there is a smaller ratio of N:O in N 2 O 3 than NO so N 2 O 3 has the smaller percentage of nitrogen. In letter c, there is an equal ratio of O:N in NO 2 than N 2 O 4 so they have the same percentage of oxygen.
