What pressure (in atmospheres) will be exerted by 1.3 moles of gas in a 13 litre flask at 22 degrees Celcius? (Gas constant (R) = 0.0821 L atm K^-1 mol^-1)

  • Chemistry -

    Use ideal gas law:

    PV=nRT (T in °K)


    =1.3 mol *0.0821 L atm °K-1 mol-1 *(22+273.16)°K/13 L
    =2.423 atm
    =2.4 atm (approx.)
