What volume will #5.2 xx 10^24# molecules of #CO_2# occupy?
Well, clearly a pellet of dry ice will occupy LESS volume than carbon dioxide gas....
And so we specify conditions of
And I make this over
At what pressure and temperature?
Do you mean at STP?
We can use the ideal gas equation: PV = nRT
(Pressure)(Volume) = (moles)(gas constant)(Temperature)
You have given me these parameters:
gas constant =
volume = x(variable)
pressure = ?(not given)
temperature = ?(not given)
If you mean at STP, where the pressure is 1 atm and the temperature is 273K, here is the equation and answer:
