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

The molarity of the solution is 0.094
`(moles)/(liter)`

Step-by-step 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=(number of moles of solute)/(volume)`

Molarity is expressed in units
`(moles)/(liter)`.

In this case:

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

Replacing:

`Molarity=(0.080 moles)/(0.850 L)`

Solving:

Molarity= 0.094
`(moles)/(liter)`

The molarity of the solution is 0.094
`(moles)/(liter)`
