How many moles of magnesium phosphate, Mg3(PO4)2 will contain 0.25 mol...
1mole of Mg3 (PO4 )2
=> 3moles of Mg atom + 2 moles of P atom + 8 moles of O atom
8 moles of oxygen atoms are present in = 1mole of Mg3 (PO4)2
0.25mole of oxygen atoms are present in = (1 x 0.25)/8
= 3.125 × 10–2moles of Mg3 (PO4 ) 2.
=> 3moles of Mg atom + 2 moles of P atom + 8 moles of O atom
8 moles of oxygen atoms are present in = 1mole of Mg3 (PO4)2
0.25mole of oxygen atoms are present in = (1 x 0.25)/8
= 3.125 × 10–2moles of Mg3 (PO4 ) 2.

8 moles of oxygen atom are contained in 1 mole of Mg4(PO4)2 0.25 moles of oxygen atoms=1/8×0.25=0.125×0.25=0.03125 so make an.normal integer.. =3.125×10^-2.....that's it ...hope u clear...!!👍😊

How many moles of magnesium phosphate, Mg3(PO4)2 will contain 0.25 mol...
Given:
Number of moles of oxygen atoms = 0.25 mol
To Find:
Number of moles of magnesium phosphate, Mg3(PO4)2
Explanation:
Step 1: Calculate the number of moles of oxygen atoms in one mole of Mg3(PO4)2
- In one mole of Mg3(PO4)2, there are 8 oxygen atoms (2 in each phosphate group)
- So, the number of moles of oxygen atoms in one mole of Mg3(PO4)2 = 8 * 0.25 = 2 mol
Step 2: Calculate the molar mass of Mg3(PO4)2
- Molar mass of Mg = 24.3 g/mol
- Molar mass of P = 30.97 g/mol
- Molar mass of O = 16 g/mol
- Therefore, molar mass of Mg3(PO4)2 = 3(24.3) + 2(30.97) + 8(16) = 262.3 g/mol
Step 3: Calculate the number of moles of Mg3(PO4)2 that contain 2 moles of oxygen atoms
- Number of moles of Mg3(PO4)2 = 0.25 mol / 2 mol = 0.125 mol
Therefore, the number of moles of magnesium phosphate, Mg3(PO4)2 that will contain 0.25 mole of oxygen atoms is 0.125 mol, which is equal to 3.125 x 10^-2 moles. Hence, the correct answer is option 'A'.
