Question

1.) A closed 5.00 L container is filled with a mixture of 4.00 moles of hydrogen gas, 8.00 moles of oxygen, 12.0 moles of helium, and 6.00 moles of nitrogen. What is the pressure in this container at a temperature of 25 °C?

2.) A closed 5.00 L container is filled with a mixture of 4.00 moles of hydrogen gas, 8.00 moles of oxygen, 12.0 moles of helium, and 6.00 moles of nitrogen. What is the pressure due to the oxygen in this container at a temperature of 25 °C?

Please explain, Thank you~
bobpursley
total moles=30moles
PV=nRT solve for P, change temps to K

b.Aren't these the same question?
(30(.08206)(298))/5

P=(ntotal(RT))/R

=147atm

for number two do the same but with 8 instead of 30
(30(.08206)(298))/5

P=(ntotal(RT))/R

=147atm

for number two do the same but with 8 instead of 30

because it is only the oxygen
