Document Summary

A gas with formula sox has a density of 2. 968 gl(^-1) at 35 deg and a pressure of 95. 09 kpa. Molar mass of the gas: mm = drt p. The value of x x = 48 g/mol = 3. Ideal gasses may be applied to any gas or mixture of gases, as long as they exhibit. Each gas in a mixture exerts a partial pressure; this is the pressure the gas would exert if it were alone in the container. The sum of all the partial pressures of the gasses in the mixture is equal to the total pressure of the gas mixture. Pt = pa + pb + pc (the partial pressures add up to the total pressure) X = moles of component a or x = pressure of component a total moles in mixture total pressure of mixture. P2 = 90. 0kpa x 0. 44 = 32. 7 kpa. P2 = 70. 0 kpa x . 76 = 44. 54 kpa.
