| **The vessel was filled with 50 liters of oxygen, 50 liters of hydrogen, 50 liters of chlorine-hydrogen. Calculate the volume fractions of each gas in the mixture.**

Given:

V (O2) = 50 l

V (H2) = 50 l

V (HCl) = 50 l

Find:

φ (O2) -?

φ (H2) -?

φ (HCl) -?

Solution:

1) Calculate the volume of the mixture:

V mixture = V (O2) + V (H2) + V (HCl) = 50 + 50 + 50 = 150 l;

2) Calculate the volume fraction of O2:

φ (O2) = V (O2) * 100% / V mixture = 50 * 100% / 150 = 33.33%;

3) Calculate the volume fraction H2:

φ (H2) = V (H2) * 100% / V mixture = 50 * 100% / 150 = 33.33%;

4) Calculate the volume fraction of HCl:

φ (HCl) = 100% – φ (O2) – φ (H2) = 100% – 33.33% – 33.33% = 33.34%.

Answer: The volume fraction of O2 is 33.33%; H2 – 33.33%; HCl – 33.34%.
