I do not understand this question at all:

In a gaseous mixture of equal masses of C₂H₆ and CO₂ , the partial pressure of the c₂H₆ is 22 mmHg. What is the partial pressure of the CO₂?

I don't understand how I am supposed to find the partial pressure of CO₂, if all I am give is one partial pressure?

You are also given mass.  Think how the amount of gas (mol) relates to pressure.
