1. how many atoms are there in 2.8 moles of carbon? you must show your work to receive credit.

2. how many moles are 1.50 x 10^23 molecules of naoh? must show work to receive credit.

you! : )

The answer to your question is

1.-  1.686 x 10²⁴ atoms

2.- 0.25 moles

Explanation:

1.-

              1 mol 6.023 x 10²³ atoms

             2.8 moles  x

              x = (2.8 x 6.023 x 10²³) / 1

              x = 1.686 x 10²⁴ atoms

2.-           1 mol 6.023 x 10 ²³ molecules

               x moles  1.50 x 10²³ molecules

              x = (1.50 x 10²³ x 1) / 6.023 x 10²³

              x = 0.25 moles                                                      

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.
