Question

Calculate the number of atCalculate the number of atoms present in
1 gram of gold (Atomic mass of Au = 198)oms present in one gram of gold.

Answer 1

Answer:

Explanation:

Atomic mass of gold (Au) = 198 g

Number of atom present in 198 gram of Au or one mole of Au =6.022 × 10^23

Number of atom present in 1 gram of Au is

= 6.022×10^23/198

=0.03041 ×10^23

=3.041×10^21 atoms

number of atom's present in 1 gram of Au is 3.041×10^21 atoms
