Determine what the mass fraction of the solute in the solution is equal to if 35 g HBrO3 and 215 ml of water were taken for its preparation.
Given:
m in (HBrO3) = 35 g
V (H2O) = 215 ml = 215 g
To find:
w (HBrO3)
Decision:
m p (HBrO3) = 35 g + 215 g = 250 g
w (HBrO3) = m w / m p * 100% = 35 g / 250 g * 100% = 14%
Answer: the mass fraction of the solute in the solution is equal to 14%
