    9.69g

    Explanation:

    To obtain the desired result, first let us calculate the number of mole of N2 in 7.744L of the gas.

    1mole of a gas occupies 22.4L at stp.

    Therefore, Xmol of nitrogen gas (N2) will occupy 7.744L i. e

    Xmol of N2 = 7.744/22.4 = 0.346 mole

    Now let us convert 0.346 mole of N2 to gram in order to obtain the desired result. This is illustrated below:

    Molar Mass of N2 = 2x14 = 28g/mol

    Number of mole N2 = 0.346 mole

    Mass of N2 = ?

    Mass = number of mole x molar Mass

    Mass of N2 = 0.346 x 28

    Mass of N2 = 9.69g

    Therefore, 7.744L of N2 contains 9.69g of N2
