The air contains 21% oxygen and 78% nitrogen by volume. Calculate the volume of oxygen and nitrogen in 250 m3 of air. Determine the amount of substance and mass for each gas.
100 liters of air contains 21 liters of oxygen and 78 liters of nitrogen, then 250,000 liters of air contains chlorine of oxygen and one liter of nitrogen.
X = 250000 * 21/100 = 52500 liters of oxygen,
y = 250,000 * 78/100 = 195,000 liters of nitrogen.
n (О2) = 52500 / 22.4 = 2343.75 mol,
m (02) = 2343.75 * 32 = 75000
n (N2) = 195000 / 22.4 = 8705.4 mol,
m (N2) = 8705.4 * 28 = 243751
Answer: 52500,195000,52500,195000,75000, 243751.2.
