A) \[45\times 6.02\times {{10}^{23}}\] atoms/mole
B) \[5\times 6.62\times {{10}^{23}}\] atoms/mole
C) \[5\times 6.02\times {{10}^{23}}\] atoms/mole
D) None of these
Correct Answer: A
Solution :
1 mole of sucrose contains \[6.023\times {{10}^{23}}\]molecules \[\because \] 1 molecule of sucrose has 45 atoms \[\therefore \] \[6.023\times {{10}^{23}}\]molecule of sucrose has \[45\times 6.023\times {{10}^{23}}\] atoms/mole
