Number of atoms in 12 g `._(12)^(24)Mg` is equal to

Number of atoms in 12 g of ""_(12)^(24)Mg is equal to

Number of atoms in 12 g of ""_(6)^(12) C is :

One mole of carbon atom weighs 12g, the number of atoms in it is equal to, ( Mass of carbon-12 is 1.9926xx10^(-23)g )

One mole of carbon atom weighs 12g, the number of atoms in it is equal to, ( Mass of carbon-12 is 1.9926xx10^(-23)g )

The number of atoms in 0.004 g of magnesium is close to (atomic mass of Mg = 24)

If 1 g of sodium carbon contains x atoms, what will be the number of atoms in 1 g of magnesium ? (C= 12u, Mg = 24 u)

The number of atoms in a 12g sample of ............is called Avogadro's number.

Find the atomic structure of ._(12)^(24)Mg . What is its valency?
