| What is the mass fraction of sulfuric acid in the solution obtained by mixing 240 g of 70% sulfuric acid solution and 320 g of 10% sulfuric acid solution?
Find the mass of acid in these two solutions:
The mass of the acid will be equal to the product of the mass of the solution by the mass fraction of the acid.
M acid = 240 x 0.7 + 320 x 0.1 = 168 + 32 = 200 grams;
The mass of the solution will be equal to:
M solution = 240 + 320 = 560 grams;
Let’s find the mass fraction of the acid. To do this, divide the mass of the acid by the mass of the total solution.
With acid = 200/560 = 0.3571 = 35.71%;
