分子量:
M :Ni(NO3)2
58.69 + (14.01+16.00*3)*2 = 182.71g/mol
M :{Ni(N2H4)3}(NO3)2
58.69 + (14.01*2+1.01*4)*3 + (14.01+16.00*3)*2
=58.69+96.18+124.02
=278.89g/mol
M :N2H4.H2O
14.01*2+1.01*4+18.02=50.08g/mol
摩尔系数比:
Ni(NO3)2 + 3N2H4.H2O = {Ni(N2H4)3}(NO3)2 + 3H2O
1 3 1 3
摩尔数是:
根据得率按80%计
{Ni(N2H4)3}(NO3)2的摩尔数是:
(30/80%)/278.89mol=0.1345mol
则 Ni(NO3)2 消耗的摩尔数是:0.1345mol
则 N2H4.H2O 消耗的摩尔数是:3*0.1345mol
质量:
Ni(NO3)2 :
0.1345mol*182.71=24.5745g
N2H4.H2O:(根据其为浓度40%)
3*0.1345mol*50.08/40%=50.5182g
不好意思刚才算错了,公家的饭不等人哈,久等了!
