# Yo what volume should 5.0g of KCl be diluted in order to prepare a 0.25 M solution?

##### 1 Answer

0.268L

#### Explanation:

Mass = 5.0g of KCl

Concentration = 0.25M KCl

Molar Mass KCl = 74.5513g/mol

Volume = ?

We can use the molarity formula to solve this, which is

However since we are trying to find the volume, we use the following formula (rearranged):

Also, our value 5.0g KCl is not in moles quite yet so we convert that in terms of moles of KCl, using the mole formula,

Next we plug in the given values into the volume formula.
