# Calculate the mass fraction of sulfuric acid in the solution formed by mixing 950 g of water and 50 ml

Calculate the mass fraction of sulfuric acid in the solution formed by mixing 950 g of water and 50 ml of 48% H2SO4 solution.

Calculate the mass of the initial sulfuric acid solution: m = p × V

m1 (pa-pa) (H2SO4) = 1.38 × 50 = 69 gr.

Let’s calculate the acid content in the initial mixture: m (in-va) = w × m (pa-pa)

m (in-va) (H2SO4) = 69 × 0.48 = 33.12 gr.

Calculate the mass of the resulting mixture: m (mixture) = m (in-va) (H2SO4) + m (H2O)

m (mixture) = 33.12 + 950 = 983.12 gr.

Let’s calculate the acid content in the resulting mixture: w2 = m (in-va) (H2SO4) / m (mixture)

w2 = 33.12 / 983.12 × 100% = 3.37%
