If I add water to 100ml of a 0.15m potassium sulfate until the final volume is 150ml what will the molarity of the diluted solution be

0.1 M is the answer and I have explained it in the attachment below.

Hope this helped!

a rain shadow is a dry region of land on the side that is protected against the prevailing winds of a mountain range. the prevailing winds are the winds that occur most of the time in a particular place of the earth

prevailing winds carry air toward the mountain range. as the air rises up over a mountain range, the air cools, water vapor condenses, and clouds form. on this side of the mountains, called the windward side, precipitation falls in the form of  rain  or snow. this dry air produces a  rain shadow.
