Compound Relative molecular mass
CH3CH2OH 46
CH3CH2OCH3 80
CH3CH2CO2CH3 88
C6H12O6 180
When 1 g of each these compunds undergoes complete combustion,which one will produce the greatest number of moles of carbon dioxide?
难道真的要把公式全列出吗?应该有更快的方法吧?

问题是
1g上述物质完全燃烧,那个产生的二氧化碳比较多
显然分子量/碳原子个数 最小的是最佳答案
23 23.3 22 30
选最后一个
