Preparation of solutions calculator is a useful tool which allows you to calculate how many solid chemicals or stock solutions you will need to prepare the desired solution. C 2 H 4 (ethylene), the industrial starting material for the plastic polyethylene. Preparation of NaNO2 solution. A compound consists of 40.7% C, 5.1% H, and 54.2% O? 1 2 3: Calculate molecular weight Molecular weights calculated on 12/28/20 : Molecular masses on 12/22/20 Molecular masses on 11/29/20 Molecular masses on 12/29/19. Equivalent weight of NaNO2 = 34.5 g. Therefore 1( M) soln of NaNO2 (69g / lit soln ) = 2 (N) NaNO2 soln 2 [ 34.5/1 lit soln] This applies for redox reaction of NaNO2 [ molar soln = 1 mole / lit soln, Normal soln = 1 g equivalent / lit soln] The molecular formula of sodium nitrite is NaNO 2. Molar mass of NaNO2 = 69 g / mol. Periodic table of the elements; Chemistry calculators; ... Molar mass = 69 g/mol . It can be calculated by adding the invididual molar mass of every atom that are composing the molecule (CH4 : 1 atom of C -> molar mass = 12.011 g/mol + 4 atom of H -> molar mass = 1.008 g/mol -> molar mass of CH4 = 12.011+4*1.008=16.043 g/mol) The molar mass of Oxygen (O) is 16.00 g / mol. I also assume that you now have to answer: What is the mole ration NaNO2: HSO3NH2. Next set up the actual mass ratio using the mass of NaNO2 that you were given. Equivalent weight of NaNO2 = Molar mass / 2 . So if you have 1.84 moles of NaNO3, you expect to collect 1.84 moles (in ideal condition of course) So in … 5. Note that the molar mass of reactant (Na(NO2)) needs to be multiplied by two because there are 2 moles of reactant in the balanced equation. Calculate the formula weight and molar mass of each compound.
