The first observer notes the time between the flash and the bang as 1.001.001.00 second. In the salt equation, Cl2 yielded the least number of grams of NaCl, therefore it is the limiting reactant. round to the hundreds place because our oxygen and carbon molar mass is only went to the hundreds We know that there are 7 mol of water formed, so we use the molecular weight of water that we just calculated to find the mass of water formed: mH2O = nH2O * MWH2O = 7 mol *18.02 g/mol = 126.14 g. As an added challenge, can you use the same method to find the mass of hydrogen that must be reacted with 3.5 mol of oxygen to form 7 mol of water? Kylene Arnold is a freelance writer who has written for a variety of print and online publications. b. Posted 2 years ago. Experts are tested by Chegg as specialists in their subject area. 3.14 mol Thus, we can read this reaction as two moles of hydrogen react with one mole of oxygen to produce two moles of water.. Balanced chemical equations are balanced not only at the molecular level, but also in terms of molar amounts of reactants and products. The molecular weight of water is: MWH2O = 2 * MWH2 + MWO2 = 2 * 1.01 g/mol + 16.00 g/mol = 18.02 g/mol. Note: The here given values are crude approximations only, that might not satisfy the task at hand.
