What is the partial pressure of argon in torr, in a container that also contains neon at 269 torr and is at a total pressure of 499 torr ?

The partial pressure is the sum of the individual pressures
so:

499 = 269 + x
429-269= x
x = 230

Pressure_argon = 230 torr

According to Dalton's law the total pressure is the sum of partial pressures, so

p(total) = p(Ne) + p(Ar)

499 = 269 + p(Ar)

p(Ar) = 499 - 269

p(Ar) = 230 torr

499 - 269 torr

All the gasses present have to add to the total pressure
