Answer:
The pressure of Cl2 is 1, 55 atm.
Explanation:
The sum of the partial pressures of the gases that make up a gaseous mixture is equal to the total pressure of said mixture, according to Dalton's law:
P total = P02 + P N2 + P Cl2
P Cl2= P total - P02 - P N2=3,30 atm-1,0 atm -0,75 atm=<em>1,55 atm</em>
