Answer:
2.76atm
Step-by-step explanation:
From the question given, we obtained the following:
Total pressure = 4.60atm
Percentage exerted by CO2 = 40%
Percentage exerted by Br2 = 100 - 40 = 60%
Therefore, the pressure exerted by Br2 will be 60% of the total pressure. This is illustrated below
=> 60% x 4.60 = (60/100) x 4.60
=> 2.76atm
