## Question:

A 0.1052 g sample of copper metal is dissolved in 55 mL of concentrated {eq}HNO_3 {/eq} to form {eq}Cu_2 {/eq}+ ions and then water is added to make a total volume of 208.5 mL.

Calculate the molarity of {eq}Cu_2 {/eq}+.

## Molarity

#### Molarity is another name for the concentration and is the number of moles of Solute per litre of solution.

#### Molarity is important when we are considering pH as well as neutralisation reactions
