    Answer:

    The total pressure of three gases is 837.56 mmHg.

    Explanation:

    The pressure exerted by a particular gas in a mixture is known as its partial pressure. So, Dalton’s law states that the total pressure of a gas mixture is equal to the sum of the pressures that each gas would exert if it were alone:

    PT = PA + PB

    This relationship is due to the assumption that there are no attractive forces between the gases.

    In this case, the total pressure can be calculated as:

    PT= 2.67 mmHg + 45.69 mmHg + 789.6 mmHg

    Solving:

    PT= 837.56 mmHg

    The total pressure of three gases is 837.56 mmHg.
