Question

2.4 moles of barium to atoms

Answer 1

number of atoms of barium = 1.445x10^24 atoms

Step-by-step explanation

Given:

number of moles of barium = 2.4 moles

Required: Atoms of barium

Solution

1 mole = 6.022x10^23 atoms

2.4 moles = x atoms

Now solve for x

x = (6.022x10^23 atoms x 2.4 moles)/1 mole

x = 1.445x10^24 atoms
