5 orange gas particles
6 blue gas particles
3 green molecules of gas (two particles attached together)
If the partial pressure of the diatomic gas is 0.390 atm, what is the total pressure?
Dalton's law says pressures are based on mole ratios.
14 total "moles'
total pressure= 14/3 * .390= you do it.
pressure blue: 6/14 * total pressure
pressure orange: 5/14 *(total pressure)
and of course, the sum of the three partial pressures should equal total pressure.
