What is the molarity of a solution that contains 0.25 mole of solute in 250 milliliters of solution

1.0 mol/dm3

Explanation:

Given that:

Amount of moles = 0.25 moles

Volume = 250 millliters of solution

Convert milliliters to liters

If 1000 milliliters = 1 liter

250 milliliters = (250/1000) = 0.25 L

Recall that 1 liter = 1dm3

so, 0.25 liters = 0.25 dm3

Now, molarity is calculated by dividing the amount of a substance by the volume of the solution.

i.e Molarity = (Amount in moles/volume in dm3)

Molarity = (0.25 moles / 0.25 dm3)

= 1.0 mol/dm3

Thus, the molarity of the solution is 1.0 mol/dm3
