Question

What will be the pressure of the gaseous mixture when 0.5 l of H² at 0.8 bar and 2 l
of dioxygen at 0.7 bar are introduced in a 1l vessel at 27ºC?

Solution

Given,
p_H = 0.8 bar
V_H = 0.5 L
p_O = 0.7 bar
V_O = 2L
Final volume, V_f = 1 L
To find, p_f
So, p_H V_H + p_O V_O = p_f V_f
0.8* 0.5 + 0.7* 2= p_f * 1
p_f = 1.8 bar
