    P (total) = 1329 torr

    Explanation:

    Given dа ta:

    Pressure of nitrogen = 984 torr

    Pressure of carbon dioxide = 345 torr

    Total pressure of system = ?

    Solution:

    The given problem will be solve through the Dalton law of partial pressure of gases.

    According to the this law,

    The total pressure exerted by the mixture of gases is equal to the sum of partial pressure of individual gas.

    Mathematical expression,

    P (total) = P₁ + P₂ + ... + Pₙ

    Here we will put the values in formula,

    P₁ = partial pressure of nitrogen

    P₂ = partial pressure of carbon dioxide

    P (total) = 984 torr + 345 torr

    P (total) = 1329 torr
