I want to know how you get the answer for the following problem: Use the periodic table to determine how many atoms of phosphorus (P) are in a sample that has
a mass of 172.90 g.
I know it's
3.36 x 10^24 atoms but I want to know how to get it because I'm currently struggling in chem with this, I'd really appreciate it if someone could explain it to me, and please don't comment just for points! I will report if I have to!

in theory, limestone is composed principally of the compound calcium carbonate - caco3, but in reality this compound is deposited in conditions involving a number of other compounds as impurities so it ends up being a mixture of many compounds.

hope this : -)
