2ch3cooh + 2mg = 2ch3coomg + h2
ню(mg)= 2 моль
m(mg)= ню * M = 2 * 24 = 48г
ню(ch3coomg)=2 моль
m(ch3coomg)= ню * M = 2*(12*2+3+16*2+24)=83*2=166г
составим пропорцию
12/48=x/166
x= 12*166 /48 = 41.5
ответ: m(ch3coomg)=41.5г
2ch3cooh + 2mg = 2ch3coomg + h2
ню(mg)= 2 моль
m(mg)= ню * M = 2 * 24 = 48г
ню(ch3coomg)=2 моль
m(ch3coomg)= ню * M = 2*(12*2+3+16*2+24)=83*2=166г
составим пропорцию
12/48=x/166
x= 12*166 /48 = 41.5
ответ: m(ch3coomg)=41.5г
