Question

8 x10^23 atoms Na to moles

Answer 1

Moles of Na = 1.328 moles

Step-by-step explanation

Given:

Atoms of Na = 8 x10^23 atoms

Required: number of moles of Na

Solution

1 mole = 6.022x10^23 atoms

x moles = 8 x10^23 atoms

solve for x

x = (8 x10^23 atoms x 1 mole)/6.022x10^23 atoms

x = 1.328 moles
