Chemistry
1 answer:
Naya [18.7K]2 years ago
3 0

Answer:

<h3>The answer is 7.23 moles</h3>

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{4.35 \times  {10}^{24} }{6.02 \times  {10}^{23} }  \\  = 7.225913...

We have the final answer as

<h3>7.23 moles</h3>

Hope this helps you

How many moles of ammonia, NH,, are contained in<br><br> 6.21 x 1024 molecules of ammonia?
ankoles [38]

Answer:

10.32 moles of ammonia NH₃

Explanation:

From the question given above, the following data were obtained:

Number of molecules = 6.21×10²⁴ molecules

Number of mole of NH₃ =?

The number of mole of NH₃ can be obtained as follow:

From Avogadro's hypothesis,

6.02×10²³ molecules = 1 mole

Therefore,

6.21×10²⁴ molecules = 6.21×10²⁴ / 6.02×10²³

6.21×10²⁴ molecules = 10.32 moles

Thus, 6.21×10²⁴ molecules contains 10.32 moles of ammonia NH₃
