1.5 M

Explanation:

We want to find the molarity of the solution, so to do so, we need two pieces of information: the moles of KOH and the volume.

We are given 10 grams of KOH, so we can convert this to moles by dividing by the molar mass of KOH, which is 39.1 + 16 + 1.01 = 56.11 g/mol. So we have:

Now, we know that the final volume is 120 mL, which is equivalent to 0.120 L, so divide 0.18 by 0.120 to get the molarity:

0.18 mol / 0.120 L = 1.5 mol/L

Thus, the answer is 1.5 M.

a  solution  is always transparent, light passes through with no scattering from solute particles which are molecule in size. the  solution  is homogeneous and does not settle out. a colloid is intermediate between asolution  and a  suspension. while asuspension  will separate out a colloid will not.
