If I place 2 moles of helium and 3 moles of oxygen in a 20 liter container at a temperature of 310 K, what is the pressure in the container

Step1 Total moles = 2+3=5 ;V=20l ; R=.082 litre atm ; T= 310K

Step2 P= nRT/V = 5x.082x310/20 = 6.355 atm

Explanation: Hope this helps.

> b takes place in the gas phase in an isothermal tubular reactor. the feed is one mole of a per one mole of c, an inert. the entering temperature and pressure are 427°c and 10 atm, respectively. the gas constant r = 0.08206 atm · l/mol · k.
