Molar mass of Na (Sodium) = 23
Weight given = 20 g
Mole = Given weight (grams)/molar mass
=> Mole = 20/23
Now number of particles = mole × Avogadro number
{Avogadro Number = 6.022 × 10²³)
=> Number of particles in 20 cm Na
= 20/23 × 6.022 × 10²³
=> 5.236 × 10²³ (approx)
=> 5.24 × 10²³ (approx)
Hope it helps dear friend ☺️✌️✌️
