Question

please do (a) part compulsary​

Answer 1

In this question at first we will find the Number of Moles:-

=> No. of Moles = Given mass/ Molar mass

=> No. of Moles = 0.056/102

=> No. of Moles = 0.00054 mol.


Now,


=> No. of Particles = No. of Moles x Avogadro's No

=> No. of Particles = 0.00054 x 6.022 x 10^23

=> No. of Particles = 3.25188 x 10^20
