Analysis of a compound shows carbon hydrogen and nitrogen present. Each molecule contains one nitrogen atom. A 150. Mg sample of the compound produces 27.4 mg of NH3 in which all the nitrogen comes from the sample. Which of the following is the formula for the compound? A. CH3N B. C2H2n C. C4h11n D. C3h13n C. C6h2n
Convert 27.4 mg NH3 to mg N, then to percent N in the 150 mg sample.
Then calculate the percent N in each of the answers. The one that matches %N in the analysis is the one to pick (although I don't think the answer is an exact match).
