Answer:
They differ by their atomic mass and have same proton number.
Explanation:
Isotopes are atoms of the same element with the same proton or atomic number but with different atomic masses.
The concentration of solution : 0.2 M

Given
5.6 g Potassium hydroxide(KOH)
500 ml of solution = 0.5 L
Required
The concentration
Solution
Molarity shows the number of moles of solute in every 1 liter of solution or mmol in each ml of solution
MW KOH = 39+16+1=56 g/mol
mol solute(KOH) :
= mass : MW KOH
= 5.6 : 56 g/mol
= 0.1
Molarity :
= 0.1 : 0.5
= 0.2 M
