How much hydrogen chloride needs to be dissolved in 1 m3 of water to get a 20% solution? Calculate the mass and volume of hydrogen chloride.
Given:
V (H2O) = 1m3
w solution (HCl) = 20%
Decision:
m (H2O) = 1000000g
x – mass of HCl
w (HCl) = x / x + 1,000,000
x / x + 1,000,000 = 0.2
x = 250,000 g (250 kg)
V (HCl) = 250000 * 22.4 / 36.5 = 153424 l = 153.424 m3
Answer: 250kg, 153.424m3
