Question

How many molecules make up 0.051 moles of Potassium chloride (KCl)?

Answer: ???? molecules KCl (no rounding; remember to use scientific notation when necessary)

Answer 1

3.0702 × 10²² molecules

Step-by-step explanation:

The number of molecules potassium chloride 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 = 0.051 × 6.02 × 10²³

We have the final answer as

3.0702 × 10²² molecules

Hope this helps you
