Answer: 344.927778
Work: T(k)=(T(°F)+459.67)x5/9
T(K)=(60°F+459.67)x5/9=288.71 K
<span>. Atoms of one element can combine with atoms of other elements to form copounds. A given compound always has the same realtive numbers and types of atoms. </span>
The total pressure is 6.7 atm. The mole fractions of O₂ and Ar are 0.42 and 0.037.
<em>p</em>(Tot) = <em>p</em>(N₂) + <em>p</em>(O₂) + <em>p</em>(Ar) + <em>p</em>(He) = 3.5 atm + 2.8 atm + 0.25 atm + 0.15 atm = 6.7 atm
χ(O₂) = p(O₂)/p(Tot) = 2.8 atm/6.7 atm = 0.42
χ(Ar) = p(Ar)/p(Tot) = 0.25 atm/6.7 atm = 0.037
