Question

How many moles of ammonia, NH3, are in 6.5x10^25 molecules of ammonia?

Answer 1

Answer:

The answer is 103.82 moles

Explanation:

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

$n = \frac{N}{L}$

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 we have

$n = \frac{6.25 \times {10}^{25} }{6.02 \times {10}^{23} } \\ = 103.82059...$

We have the final answer as

103.82 moles
