Question

How many formula units are in 8.70X10^5 moles of CuCl2?

Answer 1

Solution:

One mole of any substance contains 6.022×10²³ formula units.

Hence,

(8.70×10⁵ mol) × (6.022×10²³ formula units / 1 mol) = 5.239×10²⁹ formula units CuCl₂

There are 5.24×10²⁹ formula units in 8.70×10⁵ mol CuCl₂.

Answer: 5.24×10²⁹ formula units in 8.70×10⁵ moles of CuCl₂.
