What is the number of moles of beryllium atoms in 36 g of be?

Explanation:

Number of moles is the number of particles present in a specific substance.  Therefore, we can calculate number of moles as follows.

    Number of moles =

Molar mass of Be is 9.0 gram/ mol. Thus, calculate the number of moles of beryllium atoms in 36 g of Be as follows.

           Number of moles =      

                               =

                               = 0.4 mol

Thus, we can conclude that there are 0.4 mol of of beryllium atoms in 36 g of Be.

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.
