calculate the volume occupied by 7g of N2 gas at 27 degree c and 750mm Hg pressure

  • Chemistry -

    p v = n r t ... v = n r t / p

    make sure the r value has the correct units

  • Chemistry -

    As we know that PV =nR T .................(1)eqn.
    First of all, we will find n =given mass / molar mass
    Then, put values in equation no. (1)
    Make sure about value of R
    Answer will be 6.239litres
