Asolution of cacl2 in water forms a mixture that is 34.5% calcium chloride by mass. if the total mass of the mixture is 477.4 g, what masses of cacl2 and water were used?

Explanation:

 Let c = mass of calcium chloride

and w = mass of water

You have two conditions:

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.
