    Formula of a metallic oxide is \[MO.\] The  formula of its phosphate will be                                              [CPMT 1986, 93]

    A)                 \[{{M}_{2}}{{\left( P{{O}_{4}} \right)}_{2}}\]       

    B)                 \[M\left( P{{O}_{4}} \right)\]

    C)                 \[{{M}_{2}}P{{O}_{4}}\]               

    D)                 \[{{M}_{3}}{{\left( P{{O}_{4}} \right)}_{2}}\]

    Correct Answer: D

    Solution :

                    Valency of metal is + 2 by formula MO so its phosphate would be \[{{M}_{3}}{{(P{{O}_{4}})}_{2}}\] because valency of \[[P{{O}_{4}}]\] is ? 3.
