Answer:

Molarity of potassium chloride is 0.100M

Explanation:

Molarity is defined as moles of solute per liter of solvent.

Moles of solute (Potassium chloride; MW: 74.55g/mol):

0.182g × (1mol / 74.55g) = <em>2.44x10⁻³mol KCl</em>

<em />

Liters of water using density are:

26.0g Water × ( 1mL / 1.071g) × (1L / 1000mL) = <em>0.0243L</em>

<em />

Thus, molarity of KCl in the sample is:

<em>2.44x10⁻³mol KCl / 0.0243L = </em><em>0.100M</em>

<em />

I hope it helps!
