Aflask contains 1/3 mole of h2 and 2/3 mol of he. compare the force on the wall per impact of h2 relative to that for he.

1/2

Explanation:

By Raoult's Law, the pressure of a gas in a gas mixture, is its mole fraction multiplied by the total pressure of the gas mixture. Thus, calling Pt as the total pressure:

The pressure is the force divided by the area, thus:

Because the area is the same:

pure water does not conduct electricity very well. however, when certain substances are dissolved in water, the solution does conduct electricity. you can make a simple device that shows how well a solution conducts electricity. this device uses a flashlight bulb to indicate how well the solution conducts electricity. the better the solution conducts electricity, the brighter the bulb will glow.
