How many moles are in 1.93x1023 particles of Na3PO4?
Tresset [83]

Answer:

<h3>The answer is 0.32 moles</h3>

Explanation:

To find the number of moles given the 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

N = 1.93 × 10²³ particles

We have

n =  \frac{1.93 \times  {10}^{23} }{6.02 \times  {10}^{23 } }  \\  = 0.320598006...

We have the final answer as

<h3>0.32 moles</h3>

Hope this helps you
