5 orange gas particles

Question

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?

Answer 1

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.

Answer 2

1.82 atm
