1. The problem statement, all variables and given/known data 5 There are four common oxides that contain only N and O. The composition of three of the compounds is shown below. According to the law of Multiple proportions, which of the four (a, b, c, d) could not be one of the four oxides of nitrogen? a. 1.000 g(N) combined with 2.8571 g(O) b. 1.000 g(N) combined with 1.1429 g(O) c. 1.000 g(N) combined with 1.7143 g(O) d. 1.000 g(N) combined with 1.5000 g(O) 2. Relevant equations x=(amount of whole substance-amount given)/amount given 3. The attempt at a solution I'm struggling badly here, any tips would be much appreciated. I don't understand how I can get the answer without knowing the grams of the whole substance (N and O together).
