Acid evaporation

How many kilograms of water do we have to evaporate from 100 kg of 32% acid to make it 80% concentration?

Final Answer:

m =  60 kg

Step-by-step explanation:

r1=80%=10080=54=0.8 r2=32%=10032=258=0.32 m0=100 kg  r1 (m0m)=r2 m0 0.8 (100m)=0.32 100  0.8m=48  m=0.848=60  m=60=60 kg
