Welding is an industrial process that is used to join pieces of metal. A certain mixture of gases used in welding is composed of carbon dioxide and argon. The partial pressure of carbon dioxide is 0.080 atm and the partial pressure of argon is 0.24 atm. What is the total pressure of the mixture?

What fraction of the molecules in the mixture are argon?

 0.32 atm

Explanation:

According to Dalton's law, the total pressure is the sum of individual pressures.

Given :  =total pressure of gases = ?

= partial pressure of carbon dioxide = 0.080 atm

= partial pressure of argon = 0.24 atm    

putting in the values we get:

Thus the total pressure of the gases is 0.32 atm

answer

i think the answer is a) as air pressure in an area increases, the density of the gas particles in that area decreases.

hope it

the product of the pressure and volume is also constant
