Question

PLEASE HELP ME ASAP PLEASE!!!!

A sealed vessel containing helium, chlorine, and fluorine has a total pressure of 205 kPa and partial pressure of 15 kPa for chlorine and 89 kPa for fluorine.
What is the partial pressure of helium in kPa?
​

Answer 1

101 kPa

Step-by-step explanation:

Dalton's law of partial pressures states that in a gaseous mixture, the partial pressure of a gaseous component is the same as the pressure that gas would exert if it alone occupied the container.
