Question

How many atoms are in 2.5 moles of c4h802

Answer 1

1.505 × 10²⁴ atoms

Step-by-step explanation:

To find the number of entities in a given substance we use 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

n = 2.5 moles

We have

N = 2.5 × 6.02 × 10²³ = 1.505 × 10²⁴

We have the final answer as

1.505 × 10²⁴ atoms

Hope this helps you
