Se amesteca 50g sirop de concentratie 10% cu 200g de solutie de sirop de concentratie 30%.Care este concentratia solutiei obtinute prin ametecarea celor doua solutii?

Răspuns :

ms1=50g
cp1=10%
ms2=200g
cp2=30%

Cp1=md1/ms1*100=>md1=10*50/100=5g

Cp2=md2/ms2*100=>md2=30*200/100=60g

mdf = 5+60=65g

msf=50+200=250g

Cpf=mdf/msf*100=6500/250=Calculeaza!
