Given that the rate of diffusion is 1 mm per 1 second. then the time it travels in 1 cm can be solve using the formula t = d / r where d is the distance r is the rate
Unless they chemically react with each other, the individual gases in a mixture of gases do not affect each other’s pressure. Each individual gas in a mixture exerts the same pressure that it would exert if it were present alone in the container . The pressure exerted by each individual gas in a mixture is called its partial pressure.
