Question

How many atoms of Kr (Krypton) are in a balloon that contains 2.00 mol of Kr? (4)

Answer 1

`atoms= 1.204x10^(24)atoms`

Step-by-step explanation:

Hello!

In this case, according to the Avogadro's number, it is possible to compute the atoms of Kr in 2.00 moles as shown below:

`atoms=2.00mol*(6.022x10^(23)atoms)/(1mol) \\\\atoms= 1.204x10^(24)atoms`

Best regards!
