In a vinegar solution, the ratio of acid to water is 2:11, respectively? how much acid do you need to take to get 780 g of solution?

Since there are two parts of acid and eleven parts of water in solution, it means that all components in solution are:
2 + 11 = 13 pieces.
Therefore, the acid in the solution is 2/13. Let us determine the mass of the acid in the solution if it is known that the mass of the entire solution should be 780 grams.
780 × 2/13 = 120 grams.
Answer: you need to take 120 grams of acetic acid.
