How many moles of hcl are in 20 ml sample of .10 m hcl

0.002 moles

Concept tested: Molarity

We are given;

We are required to calculate the number of moles of HCl

What is molarity?

How is it calculated?

To calculate the number of moles we rearrange the formula;

Moles = Molarity × Volume

In this case;

Moles of HCl = 0.10 M × 0.02 L

                      = 0.002 moles

Therefore, the number of moles of HCl is 0.002 moles
