Find the mass fraction of sulfuric acid if 50 g of acid was dissolved in 200 g of water.
June 22, 2021 | education
| Given:
m (H2O) = 200 g
m (H2SO4) = 50 g
To find:
ω (H2SO4) -?
Decision:
1) m solution (H2SO4) = m (H2O) + m (H2SO4) = 200 + 50 = 250 g;
2) ω (H2SO4) = m (H2SO4) * 100% / m solution (H2SO4) = 50 * 100% / 250 = 20%.
Answer: Mass fraction of H2SO4 is 20%.
