Correct Question:

Number of particles in :-

(a) 48g of sodium atoms

(b) 8g of oxygen atoms

(c) 0.1 mole of CO2 molecules

Required Answer:

(a) 48g of sodium atoms

We know that,

▪️1 mole of Na atoms = 6.022 × 10²³ atoms

=> 46g of Na atoms = 6.022×10²³×46/23

=> 46g of Na atoms = 1.2044×10²⁴ atoms

 \\

(b) 8g of oxygen atoms

We know that,

▪️1 mole of O2 molecules contain = 6.022×10²³ atoms.

=> 8g of O2 molecules = 6.022×10²³×8/32

=> 8g of O2 molecules = 1.5055×10²³ molecules

 \\

(c) 0.1 mole of CO2 molecules

We know that,

▪️1 mole of carbon atoms = 6.022×10²³ atoms

=> 0.1g carbon atoms = 6.022×10²³×0.1

=> 0.1g carbon atoms = 6.022×10²² atoms
