Calculate the number of moles of iodine in 7.68×10^25 molecules of I2

Dmitrij [34]

Answer:

<h2>127.57 moles</h2>

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

$n = \frac{7.68 \times {10}^{25} }{6.02 \times {10}^{23} } \\ = 127.574750...$

We have the final answer as

<h3>127.57 moles</h3>

Hope this helps you
