Question

How many moles are in 19.6 g of Sodium (Na)? And the conversion factor?

Answer 1

n=0.852 moles

Step-by-step 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.

`n=(m)/(M)\\\\n=(19.6)/(22.99)\\\\n=0.852`

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