    Answer: The volume of the gas is 178.76 L

    Explanation:

    The ideal gas equation is given as:

    …….(1)

    where

    P = pressure of the gas = 675 torr

    V = volume of gas = ?

    n = number of moles of gas = 6.45 moles

    R = Gas constant = 62.36 L.torr/mol.K

    T = temperature of the gas = 27^oC=[27+273]K=300K

    Putting values in equation 1, we get:

    675torr\times V=6.45mol\times 62.36L.torr/mol.K\times 300K\\\\V=\frac{6.45\times 62.36\times 300}{675}=178.76 L

    Hence, the volume of the gas is 178.76 L
