Answer #1

    Total volume of tube = 20.4ml

    The test tube contains gas and water

The volume of gas and water = 20.4ml

volume of water                       = 4.7ml

Volume of gas = The volume of gas and water- volume of water

                           = 20.4-4.7   = 15.7ml

volume of gas     = 15.7ml
