Amixture of three noble gases has a total pressure of 1.25 atm the individual pressures exerted by neon and argon are 0.68 atm and 0.38 atm respectively. what is the partial pressure of the third gas ,helium

0.19 atm

Explanation:

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

Given : = 1.25 atm

= 0.68 atm

= 0.38 atm

= ?

Putting in the values:

Thus partial pressure of the third gas helium is 0.19 atm
