Answer:
[tex]20.33\times 10^{26}[/tex] atoms
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 :
[tex]n=\dfrac{13200}{39.0983 }\\\\=337.61\ \text{mol}[/tex]
Let there are x atoms in 13200 g of potassium (k). It can be calculated :
[tex]x=n\times N_A\\\\=337.61\times 6.023\times 10^{23}\\\\=20.33\times 10^{26}[/tex]
So, there are [tex]20.33\times 10^{26}[/tex] atoms.
