c

law states: If two elements form more than one compound between them, then the ratios of the masses of the second element which combine with a fixed mass of the first element will be ratios of small whole numbers.

no is 1:1 ratio of n to o, no2 is mass ratio of 1:n to 2 o, "then the ratios of the masses of the second element which combine with a fixed mass of the first element will be ratios of small whole numbers."

n is fixed, and o is in a ratio of small whole numbers!
