One mole of any Substance contains of Atoms/molecules of present in the 100 mL of 0.02M solution is
(i) molecules
(ii) molecules
(iii) molecules
(iv) molecules
The answer is the option (i) molecules.
Explanation:
Given: Molarity = 0.02 M
Given; Volume of solution = 100ml = 0.1 L
Number of moles Of = Molarity × Volume ( litres)
Number of molecules of =
Number of molecules = Molecules
