Acid solution

By adding 250 grams of a 96% sulfuric acid solution to its 3% solution, we changed its initial concentration to 25%. How many grams of 3% of the acid was used for dilution?

Correct answer:

x =  806.8182

Step-by-step explanation:


250•0.96+x•0.03 = 0.25•(x+250)

0.22x = 177.5

x = 8875/11 ≈ 806.818182
