D) One mole of phosphorus pentaoxide
Correct Answer: C
Solution :
\[\underset{\begin{smallmatrix} \text{(Cal}\text{. phosphide)} \\ \text{ 1 mole} \end{smallmatrix}}{\mathop{C{{a}_{3}}{{P}_{2}}}}\,+6{{H}_{2}}O\to \underset{\begin{smallmatrix} \text{phosphene} \\ \text{ (2 moles)} \end{smallmatrix}}{\mathop{2P{{H}_{3}}}}\,+3Ca{{(OH)}_{2}}\]
