Explanation:
According to the Question
It is given that,
- Atomic Mass of Sodium = 23 ( Molar Mass)
- Number of moles in 46 g of sodium .
we have to calculate the number of moles in 46 g of sodium .
For calculating the number of moles
we will use the following Formulae
- No. of moles = Given Mass/ Molar Mass
by substituting the value we get
⇢ No. of Moles = 46/23
⇢ No. of Moles = 2
- Hence, the number of moles in 46 g of sodium is 2 .
So, the required option is (b) 2 .
