How many moles are present in 2.3 x 1023 molecules of NH3?

avanturin [10]

Answer:

<h2>0.38 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

$n = \frac{2.3 \times {10}^{23} }{6.02 \times {10}^{23} } = \frac{2.3}{6.02} \\ = 0.382059...$

We have the final answer as

<h3>0.38 moles</h3>

Hope this helps you
