Your question could be more specific, however, i will answer it. Assuming most coffee beans have the molecular makeup of C8-H10-N4-O2, we can figure the amount of coffee mol
…ecules in a can of coffee. First, we find the molecular weight of this compound, which happens to be 194.206 grams per mole. Every coffee can differs slightly, but from what i have found, a coffee can contains approximately 360 grams of coffee, or 360 grams of C8-H10-N4-O2. Now because a mole (chemical unit of measurement) of this molecule has a mass of 194.206 grams, we can mathematically infer that in 360 grams of coffee, there is 1.853701739 moles of the coffee molecule in this can. Since a mole of any substance is defined as 6.022x10^23 particles (in our case, molecules), we can mathematically find that their are 1.116299187x10^24 coffee molecules in a can of coffee. That is 1,116,299,187,000,000,000,000,000 molecules. And molecules are made up of even smaller atoms, which you asked for. In one coffee molecule, their are 8 carbon atoms, 10 hydrogen atoms, 4 nitrogen atoms, and 2 oxygen atoms. after extensive math is done, we find there to be: 8.93393498x10^24 carbon atoms 1.116299187x10^25 hydrogen atoms 4.465196748x10^24 nitrogen atoms 2.23259837x10^24 oxygen atoms after addition, we find the total number of atoms in a can of coffee to be: 2.679472197x10^25 atoms! -JNN (MORE)
