How many atoms of oxygen are contained in 88.2 kg of aluminum carbonate? write value in e-notation with at least three significant figures. the molar mass of aluminum carbonate is 233.99 g/mol, but you will need to write the formula so that you can define the counting relationship.

There are 2.04x10²⁷ atoms of O

Explanation:

Aluminum carbonate's formula is: Al₂(CO₃)₃

This compound has 2 moles of Aluminum and 3 moles of carbonate, and carbonate has 1 mol of C plus 3 moles of O. Finally we have 9 moles of O.

9 moles of O, are in 1 mol of salt which weighs 233.99 grams

So if in 233.99 g of salt are ___ 9 moles O

88200 g of salt ___ are  (88200 . 9) / 233.99 = 3392.4 moles of O

1 mol of O __ has __ NA atoms

3392.4 moles of O __ has ___ (3392.4 . NA) / 1 =  2.04x10²⁷

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.

it means there are 3 atoms of oxygen
