Answer:
25 liters of the 16% solution should be added.
Step by Step Explanation:
pure acid amount + pure acid amount = total pure acid amount
So,
0.02*10 + 0.16*x = 0.12*(10+x)
0.02*10 + 0.16x = 0.12*10 + 0.12*x
0.16*x - 0.12*x = 0.12*10 - 0.02*10
(0.16 - 0.12)*x = 0.12*10 - 0.02*10
x = (0.12*10-0.02*10)/(0.16-0.12)=25
Check: (0.2*10+0.16*25)/(10+25) = 0.12 = 12% of concentration of the final mixture. ! Correct !
