A) \[0.05\] gram atoms and \[3.1\times {{10}^{23}}\]atoms
B) \[0.5\] gram atoms and \[3.01\times {{10}^{23}}\]atoms
C) \[0.5\]gram atoms and \[3.1\times {{10}^{23}}\]atoms
D) \[0.2\] gram atoms and \[3.1\times {{10}^{23}}\]atoms
Correct Answer: B
Solution :
Number of gram atoms of\[Ca\] \[=\frac{20}{40}=0.5\]gram atoms Number of atoms of\[Ca\] \[=0.5\times 6.023\times {{10}^{23}}=3.01\times {{10}^{23}}\]atoms
