How many moles of KOH are present in a 25 g sample of the substance? In a reaction between sulfur and oxygen, 80 g of sulfur dioxide is formed. What mass of sulfur ... WebWe know that the atomic number of krypton is 36 and the atomic average mass number is about 84. Neutron = 84 – 36 = 48. Therefore, a krypton atom has forty-eight neutrons. Based on the atomic number, mass number, and neutron number of the element, three things can be considered. These are isotope, isobar, and isotone. WebProblem, 47 says to get the empirical formulas and names for each of the ionic compounds containing, um, ... um, we would need three left. Ian's equal the positive three charge that would balance up at nitrogen. So that's the empirical formula bear. And then the name for this compound would be with him.
