Answer:

n=0.852 moles

Explanation:

Given mass is, m = 19.6 g

The molar mass of sodium is, M = 22.99 u

We need to find the no of moles in 19.6 of Sodium. We know that, no of moles is equal to given mass divided by molar mass.

[tex]n=\dfrac{m}{M}\\\\n=\dfrac{19.6}{22.99}\\\\n=0.852[/tex]

So, there are 0.852 moles in 19.6 g of Sodium.
