    The formula of a phosphate of a metal\[M\], is\[MP{{O}_{4}}\]. The formula of its nitrate will be

    A) \[MN{{O}_{3}}\]                              

    B) \[M{{(N{{O}_{3}})}_{2}}\]           

    C) \[M{{(N{{O}_{3}})}_{3}}\]           

    D)        \[{{M}_{2}}{{(N{{O}_{3}})}_{2}}\]

    Correct Answer: C

    Solution :

    Formula of metal phosphate is\[MP{{O}_{4}}\]. So, oxidation state of\[M\]is\[+III\]. \[\therefore \]Formula of metal nitrate is\[M{{(N{{O}_{3}})}_{3}}\].
