Isotopes of an element will contain the same number of protons and electrons but will differ in the number of neutrons they contain. In other words, isotopes have the same atomic number because they are the same element but have a different atomic mass because they contain a different number of neutrons.

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
