    You're going to have to use the formula PV=nRT P is the pressure V is your volume n is the number of moles R is the ideal gas constant T is your temperature

    The Pressure would have to be in atmospheres in order to use 0.0821 as your R value and your temperature has to be in Kelvin instead of celcius

    202.6kPa is equal to 2.0atm so thats your pressure that you can use in the formula 127+273=400K so you can use 400K as your temperature

    P=2.0atm V=4.0L n=unknown R=0.0821L-atm/mole-K T=400K Put them into the formula to solve for n

    \[\frac{ pV }{ RT } = n \]
