In a mixture of 2 gases (co2 and br2), 40.0 percent of the total gas pressure is exerted by the carbon dioxide. If the total pressure is 4.60 atm, what pressure does the bromine gas exert?

2.76atm

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
