pV=nRT

T = 295 K

V = 0.5 L = 0.5*10-3 m3

p = 1.442 bar = 144200 Pa

R = 8.314 J/mol*K

n = pV/RT = (144200*0.5*10-3)/(8.314*295) = 0,029 mol.

Flourine gas is in a 5.0 L container that is 25 C and 2 atm. A certain amount of hydrogen with a partial pressure of .5 is added to the container. What is the mole ratio of hydrogen?

total pressure is 2 atmFlourine+.5 atmHydrogen=2.5 atmtotalremember that pH/ptot=nH/ntot=vh/vtot so the mole ratio of hydrogen to the mixture is is .5/2.5=.2 molHydrogen to 1 moltotal
