Find the two answers that best correspond to the original version of the novel: In the drawing-room Hugh Chandler had taken his _ off the wall and was going to load it when

2KOH+ H2SO4 = K2SO4 +2H2O

m(K2SO4)=39*2+32 + 4*16 =78+32+64=174г/моль

m(KOH)=2* M (КОН)=112г.

ответ:m (КОН)=112г.

2KOH+H2SO4=K2SO4+2H2O

m(K2SO4)=174 г

n(K2SO4)=m/M=174/174=1 моль

n(K2SO4)/1=n(KOH)/2

=>n(KOH)=2 моль

m(KOH)=n*M=2* 56=112 г
