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.
m (H20) = 1,000,000 g
w (HCI) = x / x + 1,000,000
x / x + 1,000,000 = 0.2 ‘
x = 250,000 g (250 kg)
V (HCI) = 250000 * 22.4 / 36.5 = 153424 l = 153.424 m3
Answer: 250 kg, 153.424 m3
