many homes in rural america are heated by propane gas, a compound that contains only carbon and hydrogen. complete combustion of a sample of propane produced 2.641g of carbon dioxide and 1.441g of water as the only products. find the emprical formula of propane

要详细过程
为什么0.375就是C3H8

如题，该化合物只含碳和氢，所以燃烧后碳都变成二氧化碳，氢都变成水
(2.641/44):(2*1.441/18)=0.375 所以是C3H8其实知道点专业英语话能知道propane就是丙烷的意思

C含量 2．641／44＝0．06MOL
H含量 1．441／18＝0．08MOL
C：H＝3／4
C3H4 丙炔
