Answer:

$\huge{ \boxed{1.993 * {10}^(11) \: moles}}$

Step-by-step explanation:

To find the number of moles in a substance given it's number of entities we use the formula;

$n = (N)/(L) \\$

where n is the number of moles

N is the number of entities

L is the Avogadro's constant which is

6.02 × 10²³ entities

From the question

N = 1.20 × 10³⁵ formula units

$n = \frac{1.2 * {10}^(35) }{6.02 * {10}^(23) } = \\ 1.993 * {10}^(11) \: moles$

We have the final answer as
