In each case, calculate the appropriate ratio to show that the information given is consistent with the law of multiple proportions. (a) Both ammonia $\left({\text{NH}}_{\text{3}}\right)\text{ and hydrazine }\left({\text{N}}_{\text{2}}{\text{H}}_{\text{4}}\right)$ are composed of nitrogen and hydrogen. Ammonia contains 0.2158 g hydrogen for every gram of nitrogen. Hydrazine contains 0.1439 g hydrogen for every gram of nitrogen. (b) Two of the compounds that consist of nitrogen and oxygen are nitric oxide, also known as nitrogen monoxide $\left(\text{NO}\right)\text{ and nitrous oxide }\left({\text{N}}_{\text{2}}\text{O}\right)$, which is also known as dinitrogen monoxide. Nitric oxide contains 1.142 g oxygen for every gram of nitrogen. Nitrous oxide contains 0.571 g oxygen for every gram of nitrogen.
