Question: how many carbon dioxide molecules are in 1 mole of carbon dioxide?
Answer: Using the formula number of moles = Mass/Mr 44/44=1 mole of CO2 present. (Mr of carbon dioxide is (2*16)+12=44 Now times by Abogadros constant: 1* 6.022*10^23=6.022*10^23 molecules of CO2 are present. Understanding the last step is critical. 1 mole, is simply a random number; just like Pi or e.
