CH3COOH
w(C) - ?
w(H) - ?
w(O) - ?
Mr(CH3COOH) = 12 * 2 + 16 * 2+1*4= 60
w(C)= Ar(C)*n/Mr(CH3COOH) *100%= 12*2/60 * 100%= 40%
w(O)=Ar(O)*n/Mr(CH3COOH)*100% = 16*2/60*100% = 53%
wH) = Ar(H)*n/Mr(CH3COOH) * 100% = 1*4/60 * 100% = 7%
II I'm thatI'm like thatI'm a taklgI'm like, I don't know.I don't know.
