1) find the mass of the potassium chloride (KCl) solution:
m solution (KCl) = m (KCl) + m solution (H2O) = 20 + 180 = 200 g
2) find the mass fraction of potassium chloride (KCl) in the solution:
ω (KCl) = m (KCl) * 100% / m solution (KCl) = 20 * 100% / 200 = 10%
Answer: The mass fraction of potassium chloride (KCl) in the solution is 10%.
