The rules are still the same, if you re in grams, what do you need to get! Lets look at an example. Say you have 3.5g copper and 6.0g silver nitrate for the equation The next step is to calculate the amount of product each reactant could form In this case the limiting reactant is silver nitrate. Lets try a problem. May 08, 2010 · A mole is most definitely a non-dimensional number. It is 6.023 * 10^23 molecules. One of the interesting properties of gases (Avogadro’s law) is that they all occupy about the same volume at the same pressure and temperature, regardless of molecular weight. That is why the ideal gas law does not have a term for mass.

You are looking for the mass of 3.53E26 atoms of silver (a mol [6.02E23 atoms] of silver weighs ~108 grams). The number that you get should be significantly less than 1E26 because... well, because one atom of anything doesn't weigh all that much. Avogadro constant is 6,023 x 10^23 (sometimes make it simple, it can be 6 x 10^23). Avogadro constant shows that for every elemnent, substance, etc.), there's always about 6,023 x 10^23 atoms in 1 mol of that type of substance. More easily, 1 mol = 6(,023) x 10^23 atoms. So, there's 12 x 10^23 atoms of Oxygen, hence there's 2 moles of Oxygen.The relative formula mass of a compound is calculated by adding together the relative atomic mass values for all the atoms in its formula. Moles are units used to measure substance amount. 602,000,000,000,000,000,000,000 (yes, 6.02 x 10 23) things!!! An amu is far too small to measure in the lab, so chemicals are measured in grams. To be of use we need to know how many 6C 12 atoms have a mass of exactly 12 grams. This number was found to be about 6.02214 x1023 atoms.
