Gen Chem 1 或者 高中AP的基础题.
两个条件：1.化合物；2.元素组成：40.45%的碳,7.92%的氢；15.73%的氮,剩下的就是氧.
求化合物的最简式.
用ratio（比例）解答好了：
C:H:N:O=(40.45%/12):(7.92%/1):(15.73%/14):[(100%-40.45%-7.92%-15.73%)/16]=3:7:1:2(注意最终结果是最简整数比）.
对了,化学式自己写了.C3H7NO2

有一种未知的化合物，它由40.45%的C（碳），7.92%的H（氢），15.73%的N（氮）和35.9%的O（氧）所组成，这种化合物的最简分子表达式是什么？
the balance oxygen指剩余的（百分数）由氧元素构成

一个示例的一个未知的生物化学化合物是发现有百分之一组成的40.45%碳、7.92%的氢、15.73%的氮和氧平衡。什么是最简单的公式,这种化合物?
