An "empty" container is not really empty if it contains air. How may moles of nitrogen are in an "empty" two-liter cola bottle at atmospheric pressure and room temperature (25 degrees celcius)? Assume ideal behavior.
if you have h2 gas in a cylinder with piston.the pressure is 800.mm Hg and the gas occupies a volume 2.40 L what will the new volume be if we change the pressure to 0.850?
