According to Dalton, the pressure exerted by a gas inside a container is proportional to the number of molecules of that gas. If 4.00 x 10^23 molecules of N2 and 2.00 x 10^23 molecules of O2 are mixed in a container they exert a total pressure of 1686 torr. What portion of that pressure (in torr units) is exerted by the N2?

When the mercury level in a barometer decreases that atmospheric pressure has
