A) \[18.1\times {{10}^{23}}\] molecules of \[C{{O}_{2}}\]
B) \[6.02\times {{10}^{23}}\] atom of carbon
C) 3 g of carbon
D) \[6.02\times {{10}^{23}}\] atoms of oxygen
Correct Answer: B
Solution :
Key Idea : One mole \[=6.02\times {{10}^{23}}\] molecules \[\because \] One molecule of \[C{{O}_{2}}\] has 1C atom. \[\therefore \] One mole of \[C{{O}_{2}}=6.0.23\times {{10}^{23}}\]atoms of carbon.
