(1)(3) = 3. To calculate molar mass of a chemical compound enter its formula and click 'Compute'. Do a quick conversion: 1 moles Ammonia = 17.03052 gram using the molecular weight calculator and the molar mass of NH3. of molecules of that substance. Tetrahedral Except where otherwise noted, data are given for materials in their standard state (at 25 °C [77 °F], 100 kPa). If you look into the periodic table, you can see that the formula mass (or a.k.a molar mass) of Nitrogen is 14.0 g/mol and Hydrogen 1.0 g/mol. We can calculate the relative molar mass of the molecule. Molar volume = 22.4 litres. 1x3= 3. add both together (14.00+3) atomic weight or molar mass= 17.
