Molar Mass Definition, Unit, Mole, Mass vs Atomic Mass, Atomic Weight, Molar of Mixtures, Examples and Calculations. Although there is no direct way to measure the number of moles of any substance, the number of moles can be calculated by knowing the molar mass of the substance.
Jun 02, 1994 · The molecular weight of NH4NO3 is 14+4+14+3*16=80. You use the same conversion factors for the different flavors of mole as you do for converting mass units (454 g-mole = 1 lbmole, etc.). The molecular weight is used to convert from mass to moles, so it is logical that it is also used to convert between mass and molar rates:
Jan 10, 2010 · Mass of Iodine needed to react with lithium The relative atomic mass of iodine is ____ So the molar mass = _____ g/mol mass = moles x molar mass So 12.5 moles = = g of iodine So, to make sure that all 10 grams of lithium reacts, we must have a minimum of 159g of iodine 4.
(The formula for ammonium nitrate is NH4NO3, Relative atomic masses: H = 1, O = 16, N = 14). Step 2: Divide the total mass of each element by the molar mass and multiply by 100 to find the % mass.
