Calculate the number of atoms in : (i)...

Calculate the number of atoms in :
(i) 0.25 moles atoms of carbon
(ii) 0.20 mole molecules of oxygen.

Text Solution

Verified by Experts

(A) No of atoms `= n xx NA = 0.25 xx 6.023 xx 10^(23) = 1.506 xx 10^(23)` atoms
(B) No of molecules `= 0.2 xx 6.023 xx 10^(23)` molecules
So numbers of atoms `= 2 xx 0.2 xx 6.023 xx 10^(23) = 2.4092 xx 10^(23)` atoms
