Имеется ввиду переход кислой соли в соль среднюю (гидросульфат в сульфат) NaHSO4 + NaOH =Na2SO4 +H2O m(NaOH)=0.1*144*1.11=15,984г n(NaOH)=15,984г/40г/моль=0,3996моль Количество NaHSO4 тоже 0,3996моль m(NaHSO4) =0,3996моль * 120г/моль= 47,952г и это получается 40% (если не сульфат 60% - значит гидросульфат40% ) Значит масса смеси - 47,952г/0,4=119,88г - а масса сульфата в свою очередь 119,88г-47,952г=71,928г NaHSO4+Ba(OH)2=BaSO4+NaOh+h2O n(BaSO4) =0,3996моль m(BaSO4) =0,3996моль*233.43 г/моль=93,28г Na2SO4+Ba(OH)2=BaSO4+2NaOН n(BaSO4) =n(Na2SO4)=71,928г/142г/моль=0,5моль m(BaSO4)=0,5моль*233.43 г/моль=116.7г
m(BaSO4) общая =116.7г+93,28г=209.9г =210г
ответ подозрительный тк сказано округлить до десятых , а получается практически 210
