Question

If you have 8.45 x 10^27 molecules of H2O, how many moles of water do you have?

Answer 1

Answer:

The answer is 14036.54 moles

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

N = 8.45 x 10^27 molecules of H2O

We have

$n = \frac{8.45 \times {10}^{27} }{6.02 \times {10}^{23} } \\ = 14036.544850...$

We have the final answer as

14036.54 moles

Hope this helps you
