Answer:
0.1M KOH
Explanation:
Dissociation
In this reaction where KOH dissociates into K+ and OH-, you see that there is 0.1mol of each ions present in the solution. Since this is a complete reaction where there is no reactant left i.e. no KOH, 0.1mol of K+/OH-, this means that there was 0.1mol of KOH, so the same value as the number of moles of products.
Knowing that molarity is mols/L, and the number of mol is 0.1mol, and the solution is 1.0L, just divide each value.
0.1/1.0L = 0.1M KOH
