500 ml of sulfuric acid contains 114 g of sulfuric acid. Calculate the mass fraction of sulfuric acid, taking into account that the density of the solution = 1.14 g / ml
1. Let’s find the mass of sulfuric acid in the resulting solution by the formula:
m (H2SO4) = p * V = 1.14 g / ml * 500 ml = 570 g
2. Let’s calculate the mass fraction of sulfuric acid in the solution by the formula:
w (solution) = m (acid) * 100% / m (solution) = 114 g * 100% / 570 g = 20%.
