Answer» (B) 3.125 × 10⁻²Explanation:Magnesium phosphate = MG3(PO4)2 (Given)Mole of oxygen ATOMS = 0.25 (Given)Thus,One mole of Mg3(PO4)2 consist of 8 MOLES of oxygen atom = 1/8x moles of Mg3(PO4)2 consist of 0.25 moles of oxygen atom = x/0.25Therefore, 0.25 mole of oxygen = 1/8 × 0.25= 3.125 × 10⁻²Therefore, magnesium phosphate will contain 3.125 × 10⁻² moles. |
