Bell-work September 25 If the partial pressure of oxygen is 2.3 kPa, the total pressure in the system is 5 kPa, and there are 8.2x10 23 particles of oxygen in the system, how many total gas particles are present?

Homework Check 1) The partial pressure of Fluorine is 300 kPa in a mixture of gasses where the total pressure is 760 kPa. If there are 3.5x10 23 particles in the sample, how many of them are Fluorine? 2) A gas sample is 25% Chlorine, 70% Nitrogen, and 5% Helium. If the partial pressure of Helium is 1.3 atm, what is the partial pressure of nitrogen? (Hint: find the total pressure first)
