Choose the correct word to complete the sentence: “The terrorists headquarters was blown ... in the army attack.” up

Пусть масса альдегида равна 100г тогда:

w(C)=54.55%=0.5455
w(H)=9.09%=0.0909
w(O)=36.36%=0.3636
n(C)=0.5455/12= 0.046

n(H)= 0.0909/1= 0.0909

n(O)= 0.3636/16= 0.022
По соотношению:
0.046 : 0.0909 : 0.022
2 : 4 : 1
=> С2H4O или СH3COH
 M(C2H4O)=12*2+1*4+16=44г/моль
