Hot air rises, while the cooler air sinks to ground level. Then the cool air heats up and rises when it reaches the equator; and the hot air reaches the poles and cools, then also sinks. Why is it then that the the higher up in the atmosphere you are the colder it is? If the hot air currents are higher up, shouldn't it be the other way around?

So I just finished a chemistry test today and I know I answered this question incorrectly. Could anyone show me the proper way of doing it?

Q. How many atoms of oxygen are in 198.00 g of Ca3(PO4)2?

I only found the number of atoms in total and did nothing to find the number of oxygen atoms. Any help would be great!
