Question

The number of atoms in 8g of sodium is x 10²³. The value of x is ____________. (Nearest integer)

[Given : N_A = 6.02 10²³ mol¹

Atomic mass ...

Accepted Answer

Given, mass of Na = 8g

Molar mass of Na = 23 gmol^-1

Weight\,of\,sodium\,atom Molecular\,mass\,of\,sodium\,atom = Number\,of\,atoms Avogadro's\,number

8g 23g = Number\,of\,atoms 6.022 10^23

Number of atoms = 8 6.022 23 10^23

Number of atoms = 2....
