How many moles of sodium chloride are in 28 grams of NaCl?

A.) .265 mole NaCl

B.) .856 mole NaCl

C.) .479 mole of NaCl

D.) 1.2 mole NaCl

Option C. 0.479 mole of NaCl

Explanation:

First, we need to find the molar mass of NaCl.

MM of NaCl = 23 + 35.5 = 58.5g/mol

Mass of NaCl = 28g

Number of mole =?

Number of mole = Mass /Molar Mass

Number of mole = 28/58.5

Number of mole = 0.479mol

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.
