Answer: 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
The molarity of a solution is 1.0 mol/dm³. It is given as number of moles divided by the volume of solution.
What information do we have:
Amount of moles = 0.25 moles
Volume = 250 millliters of solution
250 milliliters = (250/1000) = 0.25 L
Recall that 1 liter = 1dm³
so, 0.25 liters = 0.25 dm³
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
