A 25 g portion of sulfuric acid H2SO4 was dissolved in 125 g of water. What is the mass fraction of sugar in the resulting solution.
Given:
m (H2SO4) = 25 g
m (H2O) = 125 g
To find:
ω (H2SO4) -?
1) m solution (H2SO4) = m (H2SO4) + m (H2O) = 25 + 125 = 150 g;
2) ω (H2SO4) = m (H2SO4) * 100% / m solution (H2SO4) = 25 * 100% / 150 = 16.67%.
Answer: Mass fraction of H2SO4 is 16.67%.
