A 7.65L holds 0.99 mol of oxygen gas at 35.55 degrees celsius. what is the pressure

3.27atm

Explanation:

The following were obtained from the question:

V = 7.65L

n = 0.99 mol

T = 35.55°C = 35.55 +273 = 308.55K

R = 0.082atm.L/K.mol

P =

PV = nRT

P = nRT/V

P = (0.99 x 0.082 x 308.55)/7.65

P = 3.27atm

i don't see a text, but i am gonna assume this *orbit* the curved path, usually elliptical, described by a planet, satellite, spaceship, etc., around a celestial body, as the sun.
