初三化学(1)H2O中H%=?(2)H2SO4中S%=?(3)NH4NO3中N%=?(1)H2O中H%=?(2)H2SO4中S%=?(3)NH4NO3中N%=?要就对完美的过程,重点在过程,所以麻烦各位人才多打几个字,要不然我看不懂,

问题描述:

初三化学(1)H2O中H%=?(2)H2SO4中S%=?(3)NH4NO3中N%=?
(1)H2O中H%=?(2)H2SO4中S%=?(3)NH4NO3中N%=?
要就对完美的过程,重点在过程,所以麻烦各位人才多打几个字,要不然我看不懂,

H% = [1×2/(1×2+16×1)]×100% 约等于11.1%
S% = [32×1/(1×2+32×1+16×4)]×100%约等于32.7%
N% = [14×2/(14×2+1×4+16×3)]×100% = 35%
