Question

What is the molar it's of a solution that has 0.080 moles of calcium chloride dissolved in 850mL of solution.

Answer 1

Answer:

The molarity of the solution is 0.094 $\frac{moles}{liter}$

Explanation:

Molarity is a measure of the concentration of that substance and is defined as the number of moles of solute that are dissolved in a given volume.

The molarity of a solution is calculated by dividing the moles of the solute by the volume of the solution:

$Molarity=\frac{number of moles of solute}{volume}$

Molarity is expressed in units$\frac{moles}{liter}$.

In this case:

• number of moles of solute: 0.080 moles
• volume= 850 mL= 0.850 L

Replacing:

$Molarity=\frac{0.080 moles}{0.850 L}$

Solving:

Molarity= 0.094 $\frac{moles}{liter}$

The molarity of the solution is 0.094 $\frac{moles}{liter}$
