How many oxygen atoms in a #300*g# mass of calcium carbonate?
We work out (i) the molar quantity of
Given the elemental makeup, in such a quantity there are
But what is a mole? It is simply a LARGE number that relates to a given mass of stuff. In
So given 3 moles of calcium carbonate, there are 3 moles of calcium, 3 moles ofcarbon, and 9 moles of oxygen atoms.
What is the mass of this quantity of oxygen atoms, and how do you know?
See here for another examples of this process.
