Molar mass Zinc chloride

ZnCl2 = 65.3 + 35.5 * 2 = 136.3 g/moles

1 mole ZnCl2 ------------- 136.3 g
x mole ZnCl2 ------------- 302.48 g

x = 302.48 / 136.3

x = 2.219 moles

1 mole --------------- 6.02x10²³ units
2.219 moles --------- y units

y = 2.219 * 6.02x10²³

y = [tex]1.335[/tex] formula units

hope this helps!.
