1.	A sample of ammonium phasphate (NH4)3 PO4contains 3.18 moles of 'H' atoms. The numer ofmoles of 'O' atoms in the sample is(1) 0.265(2) 0.795(3) 1.06(4) 4.00
Answer» Answer: (3) 1.06 Explanation: 1mole compound contains 12mole of H ATOMS. 1mole H atoms is PRESENT in 1/12mole of compound. 3.18mole H ATOM is present in 3.18/12 or 0.265 mole of compound. 1 mole compound contains 4 moles of O atoms. Hence, .265mole compound will have (.265x4) or 1.06 moles of O atoms.

Answer»

Answer:

(3) 1.06

Explanation:

1mole compound contains 12mole of H ATOMS.

1mole H atoms is PRESENT in 1/12mole of compound.

3.18mole H ATOM is present in 3.18/12 or 0.265 mole of compound.

1 mole compound contains 4 moles of O atoms.

Hence, .265mole compound will have (.265x4) or 1.06 moles of O atoms.
