What is the number-average molar mass of a polymer sample?

Enter a chemical formula to calculate its molar mass and elemental composition. Molar mass of (NH 3 ) 2 SO 4 is 130.1236 g/mol. 2 × [NH3(g) + H2S(g) →← NH4HS(g)] Kp = (8.3 × 10−3)2. N2(g) + 3 H2(g) ... empirical mass × n = molar mass empirical mass for CH2 = 14 g mol−1. 14 g ... When calculating consumption of certain RO chemicals for reverse osmosis pretreatment or post-treatment, it is often necessary to convert into moles. involving NH3/NH4+ in plant cells (6). An equation may be written for the molar flux density, J (nmol m-2 s-'), of ammonia into the leaf through stomata: J ... Jun 10, 2014 ... NH3, or ammonia, has a molar mass of 17.031 g/mol. So .500 moles of the substance would equal 8.5155 grams. Do a quick conversion: 1 grams NH3 = 0.058718113128665 mole using the molecular weight calculator and the molar mass of NH3. Thus, the molar mass of the given chemical compound ammonia ( N H 3 ) is 17.03052 gram per mole. Help improve Study.com.
