Question

How many atoms are there in 13200 g of potassium (k)

Answer 1

`20.33* 10^(26)` atoms

Step-by-step explanation:

Given that,

Given mass = 13200 g

Molar mass of potassium = 39.0983 g/mol

Let there are n number of moles. It is equal to mass divided by molar mass. It is equal to :

`n=(13200)/(39.0983 )\\\\=337.61\ \text{mol}`

Let there are x atoms in 13200 g of potassium (k). It can be calculated :

`x=n* N_A\\\\=337.61* 6.023* 10^(23)\\\\=20.33* 10^(26)`

So, there are
`20.33* 10^(26)` atoms.
