Question

REPEDE VA ROG! AM NEVOIE URGENTA!!!!!!

Answer 1

c/100= md/ms----> md= cxms/100               ro= m.v--> m=roxv
in solutia obtinuta,
c3/100=(md1+md2)/(ms1+ms2+m,apa)

md1= 0,4x1,23xVs1
md2= 0,2x1,04xVs2= 0,2x1,04x2Vs1
md1+md2=0,92Vs1

ms1+ms2+m,apa= 1,26Vs1+1,04x2Vs1+ m,apa unde 
                        m,apa= roxVapa= 1g.mlx (Vs1+Vs2)=Vs1+2Vs1=3Vs1

c3/100=0,92Vs1/ 6 ,34Vs1---> c3=14,51%

ms1/ms2= 1,26Vs1/ 1,04x2Vs 1=0,6
