if 1g of carbon contains x atoms,what will be the number of atoms in 1 g of magnesium?
This is the correct answer......
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.
1/12 mole of magnesium = x atoms
1/24 mole of magnesium = x x 12/24 ( x multiplied by 12, divide by 24)
= x/2 atoms
1 gram of magnesium has x/2 atoms.
hope u got plshh thubs up!!
