Two gases are combined and sealed in a 2.0 L container. The 3.0 L of argon gas and 1.0 L of xenon gas each exert 1.00 atm pressure on the walls of their container. (a) Calculate the partial pressure of each gas in the 2.0 L container.
(b) What is the total pressure in the 2.0 L container?

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.

Explanation:

weight of any object is given by

w = m*g

where m is mass of the object and g is the acceleration due to gravity.

for earth the value of g is 9.8 m/s^2 so

w=117.6 n m=12 g=?

117.6=12g => g=9.8 m/s^2

which is the force of gravity on earth.
