Question

How many moles are there in 9.6 x 10²⁵ atoms of Oxygen?

Answer 1

Answer:

The answer is

159.47 moles of oxygen

Explanation:

To find the number of moles given the number of entities of an element 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 = 9.6 x 10²⁵ atoms of Oxygen

So we have

$n = \frac{9.6 \times {10}^{25} }{6.02 \times {10}^{23} } \\ = 159.46843...$

We have the final answer as

159.47 moles of oxygen
