    If three unreactive gases having partial pressures \[{{P}_{A}},{{P}_{B}}\] and \[{{P}_{C}};\] their moles are respectively \[1\text{ }mole,\] \[2\text{ }moles\] and \[3moles,\]then their total pressure is

    A)  \[P={{P}_{A}}+{{P}_{B}}+{{P}_{C}}\]

    B)  \[P=\frac{\sqrt{{{P}_{A}}+{{P}_{B}}+{{P}_{C}}}}{3}\]

    C)                  \[P=\frac{{{P}_{A}}+{{P}_{B}}+{{P}_{C}}}{6}\]

    D)  none of these

    Correct Answer: A

    Solution :

    If three unreactive gases having partial pressure\[{{P}_{A}},\] \[{{P}_{B}}\]and \[{{P}_{C}}\] then the total pressure is represented as \[P={{P}_{A}}+{{P}_{B}}+{{P}_{C}}\]
