A) \[6.02\times {{10}^{23}}\]
B) \[3.01\times {{10}^{23}}\]
C) \[2.5\times {{10}^{23}}\]
D) \[1.5\times {{10}^{23}}\]
Correct Answer: B
Solution :
| [b] \[\because \] 2gm of hydrogen \[=6.02\times {{10}^{23}}\]molecules |
| \[\therefore \] 1gm of hydrogen |
| \[=\frac{6.02\times {{10}^{23}}}{2}=3.01\times {{10}^{23}}\]molecule. |
