3. John Dalton knew of the existence of at least three Oxides of Nitrogen. At the time, these were known as: Nitrous Gas, Nitrous Oxide and Nitric Acid. Nitrogen reacts with 1.000g of Oxygen in the following proportions to form each of these compounds: Compound Nitrous Gas Mass Nitrogen 0.875g Nitrous Oxide Nitric Acid 1.750g 0.438g 4. Dalton assigned a formula of NO to the compound Nitrous Gas. Based on this, and the above data, what formulas did he assign to Nitrous Oxide and Nitric Acid? Dalton had determined the atomic weight of Oxygen to be 7 amup. Based on this, and the above data for Nitrous Gas, what is the atomic weight of Nitrogen? Berzelius initially assigned an atomic weight of 100 amup to Oxygen. What atomic weigh would he calculate for Nitrogen? Currently, we accept that the atomic weight of Oxygen is 16 amu. Based on this assignment, and the above data for Nitrous Gas, explicitly determine the atomic weight of Nitrogen.
