Question

(c) Calculate the mass of ca that wil contain the same number of atoms as are present in 302 gm of
sulphur [S=32, Ca=40]​

Answer 1

first, let us calculate the number of atoms present in the given sample of sulphur.

∴

Now we know the no. of atoms in the given sample of Sulphur.

to find the mol of Calcium with equal atoms,

we need to divide the obtained result by Avogadro's constant

now, we know the mole

∴ 4g of Calcium will have the same number of atoms as 3.2g of Sulphur.
