Question

5. Calculate the mass of:
a) 1.6 gram atoms of oxygen
b) 5.6 gram atoms of sulphur
c) 2.4 gram atoms of iodine
(Atomic masses: 0 = 16,5 = 32,1 = 127)​

Answer 1

Explanation:

Weight of S =6.4 g

Atomic weight of S =32 g/g atom

Number of gram atoms of S =32 g/gatom6.4 g=0.2 gram atoms.

The Avogadro's number is 6.023×1023 atoms/ g atom

The number of atoms of S =0.2 gram atoms  ×6.023×1023 atoms/ g atom

=1.2×1023 atoms
