How many moles are in 9.25E24 formulas units of sodium acetate?

Lelu [443]

Answer:

<h2>15.37 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

$n = \frac{9.25 \times {10}^{24} }{6.02 \times {10}^{23} } \\ = 15.365448...$

We have the final answer as

<h3>15.37 moles</h3>
