A) \[18.1\times {{10}^{23}}\]molecules of\[\text{C}{{\text{O}}_{\text{2}}}\]
B) \[~6.02\text{ }\times \,\,{{10}^{23}}\] 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\[C{{O}_{2}}=6.02\times {{10}^{23}}\] atoms of carbon.
