Mixed 400 g of a 12% acid solution and 600 g of a 16% acid solution. Find the concentration of the resulting mixture.

Concentration is a value that shows the ratio of the mass of a solute to the mass of the entire solution. Based on this definition, let’s solve the problem.
Find the mass of acid in the first solution:
400 * 12/100 = 48 grams
Find the mass of acid in the second solution:
600 * 16/100 = 96 grams
Let’s find the total mass of acid in the final solution:
48 + 96 = 144 grams
Let’s find the mass of the entire final solution:
400 + 600 = 1000 grams
Let’s find the acid concentration in the final solution:
(144/1000) * 100% = 14.4%
Answer: You get a solution with an acid concentration of 14.4 percent.
