Question

How many molecules are in 3 moles of CO2?

O A. 5.418 x 1024
OB. 1.806 x 1024
O C. 6.02 x 1024
O D. 1.806 x 1023

Answer 1

Answer: OB. 1.806 x 1024

Step-by-step explanation:

Answer 2

1.806 × 10²⁴

Step-by-step explanation:

The number of molecules can be found by using the formula

N = 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 = 3 × 6.02 × 10²³

We have the final answer as

1.806 × 10²⁴

Hope this helps you
