How many moles are there in 7.57 x 10^30 molecules of CO2?

Answer 1

Answer:

The answer is

12,574,750.83 moles

Explanation:

In order to find the moles of CO2 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 = 7.57 × 10^30 molecules of CO2

We have

$n = \frac{7.57 \times {10}^{30} }{6.02 \times {10}^{23} } \\ = 12574750.83056...$

We have the final answer as

12,574,750.83 moles

Hope this helps you
