<strong>Molarity</strong> = <strong>moles</strong> <strong>solute</strong><br />

<strong>liters</strong> <strong>solution</strong><br />

<strong>Another</strong> <strong>way</strong> <strong>to</strong> <strong>express</strong> concentration (relationship between <strong>solute</strong><br />

and <strong>solution</strong>)<br />

We represent <strong>Molarity</strong> as a unit with a "M" which means "mol<br />

<strong>solute</strong> per L <strong>solution</strong>"<br />

We read M as "molar" out loud. For example 6.0 M KCl… we say:<br />

"6.0 molar KCl" = 6.0 <strong>moles</strong> KCl in 1 liter <strong>solution</strong> = 6.0 <strong>moles</strong> KCl<br />

1 liter <strong>solution</strong><br />
