(HELP PLEASE)
An open flask in a lab fridge looks empty, but we know that it is actually filled with a mixture of gases called air. If the flask volume is 1.50 L and the air is at standard temperature and pressure, how many gaseous molecules does the flask contain?

anonymous · Answer

try using the ideal gas eqation: PV=nRT

anonymous · Answer

wouldn't it be P=RnT/V?

anonymous · Answer

once you get moles you will need to convert to molecules

anonymous · Answer

it should be n=pv/rt

anonymous · Answer

then answer should be 4.032x10^22 molecules
