Question

if 9 g of aluminum contains same no. of atoms as that of magnesium then calculate the mass of magnesium​

Answer 1

Answer:

100 grams of magnesium: 

1 mole of Mg atom =  atoms

This means 24g of Mg has   atoms

Then 100 g contains:

Number of Mg atoms= 

Number of atoms= 

Number of Mg atoms =  atoms 

100 grams of aluminium:

1 mole of atom=  atoms

This means 27g of  has  

Then 100 g contains:

Number of  atoms= 

Number of  atoms

Number of  atoms=  atoms

Thus, 100g of magnesium has more atoms.
