Calculate the no. Of moles of iron in a sample containing 10^22 atoms

1.	Calculate the no. Of moles of iron in a sample containing 10^22 atoms of iron.
Answer» 1 MOLE of IRON = 6.02 * 10^23 ATOMS 10^22 atoms of iron = 10^22/6.02 * 10^23 = 1/60.2 = 0.0166 MOLES. Number of moles = 0.0166 moles.

Calculate the no. Of moles of iron in a sample containing 10^22 atoms of iron.

Answer»

1 MOLE of IRON = 6.02 * 10^23 ATOMS

10^22 atoms of iron = 10^22/6.02 * 10^23

= 1/60.2

= 0.0166 MOLES.

Number of moles = 0.0166 moles.
