If 2.0 mol of gas a is mixed with 1.0 mol of gas b to give a total pressure of 1.6 atm, what is the partial pressure of gas a and b?

Gas A=1,06 atm

Gas B=,53 atm

Explanation:

YOu have 3 moles of two different gases mixed into an specific container, the partial pressure is the pressure that each one of them would have if contained in the same container by themselves, as you have 3 moles of substance you just divde 1,6 atm by the 3 moles and assign each gas its correspondent pressure:

1,6/3=,53

Gas A=1,06 atm

Gas B=,53 atm

it's a b and

it is b. absorbs thermal energy
