An organic compound containing only C,H and Br was found to contain 12.8 % by mass carbon and 1.79 % by mass hydrogen.Determine the empirical formula of the compound
答
该化合物的分子式为，C3H5Br3.
答
这题应该简单,我想回答应该不用用英文回答吧；或许你对题目不了解.大致意思如下：一个有机物化合物只含有C,H,Br三种元素,其中C占12.8%,H占1.79%,问这个化合物的结构简式.C,H,Br的相对原子质量分别为12,1,80,而又一直...
