Question

If 1 gram of carbon contains x atoms so 1g of magnesium has how many atoms

Answer 1

1 mole of carbon = gram molecular mass of carbon = 12 grams.

12g carbon = 1 mole

1g carbon = 1/12 mole

1g of carbon contains x atoms and 1g = 1/12 mole.

Therefore 1/12 mole of carbon has x atoms.

Equal number of moles of all the elements contain equal atoms, so 1/12 mole of magnesium also contains x atoms.

1 mole of magnesium = 24g

Therefore, 24 gram = 1 mole

1g = 1/24mole.

1/24 mole of magnesium = ( x * 12)/ 24 ( x multiplied by 12, divide by 24)

= x/2 atoms
