What is the molarity of 2.0 liters of an aqueous solution that contains 0.50 mol of potassium iodide

0.25M

Explanation:

We can apply the following formula to find molarity ,since the Molarity (M) is the number of moles of solute per liter of solution.  

of KI(potassium iodide)

we can substitute the values to find the molarity

So the molarity of 2.0 liters of an aqueous solution that contains 0.50 mol of potassium iodide is 0.25M

Explanation:

Molarity could be defined as the amount of solute (in moles) dissolved in  1 litre of water to give its solution. It can also be referred to as the concentration of the resulting solution.

The molarity is thus calculated as follows;

the answer for apex is the lowest

as we know our atmosphere or air have different levels. every level has other gasses, and every gas has another permeability. when the light comes from lower permeability to higher permeability, it changes its direction. so that means that when the light comes from the moon to the earth, it changes it's direction many more times. it basically means that the shape of the light part of the moon is changed on the earth.
