WS 5.5 Partial Pressures (Dalton's Law)don't forget unitsp = (mol frac) x (P)1.A flask contains Ne at 542 mmHg together with Ar at 234 mmHg. What will the total pressure be?(use Dalton's law)
_2.A tank is filled with oxygen and nitrogen. The total pressure of the tank is 6.45 atm, and the partial pressure of the nitrogen is 2.07 atm. What is the partial pressure of the oxygen? (use Dalton's law)Ans 3.a) A mixture contains 1.00 moles of CO2, 2.00 moles He, and 3.00 moles of CH4. Which gashas the highest partial pressure?_Which gas has the lowest partial pressure? b) If the total pressure of the mixture above is 12.0 atm, what is the PCO2?_PHe? _____PCH4? 4.a) 1.25 moles of N2 and 6.41 moles of F2 are placed together in a 128 L tank at 755 mmHgWhat is N2's mole fraction in the mixture? What is the partial pressure of the N2?___.
_b)What is F2's mole fraction, and what is the partial pressure of the F2?b)Ans: _c)What must the temperature (˚C) of the mixture be?_
