Question

Calculate the no of atom in 120g of CH3 CooH

Answer 1

Answer:

12.044×10^3 atom

Explanation:

Molar mass of CH3COOH= 60g

Then, no. of mole = Given molar mass of CH3COOH÷ Molar mass of CH3COOH

=120÷60

= 2 moles

No.of atom = 2× 6.022×10^3 [ 1 mole = 6.022×10^3 atom]

= 12.044×10^3 atom
