英语化学求分子式和试验试!A compound contains only carbon,hydrogen,and oxygen.Combustion of 10.68 mg of the compound yields 16.01 mg CO2 and 4.37 mg H2O.The molar mass of the compound is 176.1 g/mol.What are the empirical and molecular for
m(C)=(16.01/44)*12=4.36636 (mg)
m(H)=(4.37/18)*2*1=0.48556 (mg)
m(O)=10.68-4.36636-0.48556=5.82808 (mg)
n(C);n(H);n(O)=(4.36636/12):(0.48556/1):(5.82808/16)=3;4;3
empirical formulas of the compound;
C3H4O3
M(C3H4O3)n=176.1,
so n=176.1/(12*3+4*1+18*3)=2
molecular formulas of the compound;
C6H8O6

empirical formula C3H4O3
molecular formula C6H8O6 (Vitamin C)
鉴于这个应该是比较初级的化学 上面的答案是对的 权作参考
其实具体分子式可以式很多种 比如
丙酮酸 C3H4O3 等等 很多种答案都是对的
