Excess of calcium orthophosphate is reacted with magnesium to form calcium phosphide (Ca_(3)P_(2)) along with magnesium oxide. Calcium phosphide on reacting with excess of water liberate phosphine gas (PH_(3)) along with calcium hydroxide. Phosphine is burnt in excess of oxygen to form P_(2)O_(5) along with water. Oxides of magnesium and phosphorous react to give magnesium metaphophate. Calculate grams of magnesium metaphosphate obtained if 1.92 gm of magnesium is taken. [Round off your answer to nearest integer]
