Question

A student wishes to prepare 65.0 mL of 0.875 M HCl from 12.0 M HCl.

What volume of the
12.0 M HCl should he/she start with?

Answer 1

A student should start with 4.74 mL of the 12.0 M HCl to prepare 65.0 mL of 0.875 M HCl from 12.0 M HCl.

What is Molarity ?

Molarity (M) is the amount of a substance in a certain volume of solution.

Molarity is defined as the moles of a solute per liters of a solution.

Molarity is also known as the molar concentration of a solution.

Formula used for the given question ;

M₁V₁ = M₂V₂

• M₁ = 12.0 M HCl.
• V₁ = ?
• M₂ = 0.875 M HC
• V₂ =  65.0 mL

M₁V₁ = M₂V₂

   V₁      =  0.875M x 65.0 mL / 12.0 M HCl.

            =  4.74 ml

Therefore , A student should start with 4.74 mL of the 12.0 M HCl to prepare 65.0 mL of 0.875 M HCl from 12.0 M HCl.
