уравнения реакции: cuo + h2 = cu + h2ozno + h2 = zn + h2oв 340г сплава 45% меди. значит меди там 340 г * 45%/100%= 153г, а цинка 340г-153г = 187г.молярная масса меди 64 г/моль. значит было восстановлено 153 г/ 64 г/моль = 2.4 моль медимолярная масса цинка 65 г/моль, было восстановлено 187г/ 65 г/моль = 2.9 моль цинка,из 1моль cuo получается 1 моль cu. значит было использoванно 2.4 моль * (64 г/моль +16 г/моль) = 192г оксида медииз 1моль zno получается 1 моль zn. значит было использoванно 2.9 моль * (65 г/моль + 16 г/моль) = 233г оксида цинка.таким образом масса исходной смеси равна: 192г + 233 г= 425 г
