that partial pressure of each gas is proportional to the moles of each gas, in this case, atoms. If blue, green, and orange have the same relative mass, then
moles orange=5
moles blue=5
moles green=3
total pressure=P
green pressure=3P/13
solve for P from given .750

Consider this molecular-level representation of a gas.
5 orange
6 green---> 3 pairs
6 blue
If the partial pressure of a diatomic gas is .750 atm, what is the total pressure?

So would it be (3)(.750)/13?
.1731 would be the answer?
.1731 would be the answer?
