Now that you have the molar mass of the solute, you need to multiply the number of grams of solute in the solution by a conversion factor of 1 mole over the formula weight (molar mass) of the solute. The problem states that 9.84 g is the actual yield. Molar … Melting Point (MP), Antimony sesquisulfide, stibnite changes its state from solid to liquid at 550°C (1022°F or 823.15K) Also known as: Antimony sulfide, stibnite; Antimony trisulfide, stibnite. 3. Mass magnetic susceptibility: 10.9×10-9 m 3 /kg Molar magnetic susceptibility: 1.327×10-9 m 3 /mol. Forsterite Mg2SiO4 Molar Mass, Molecular Weight. Colloform - Forming from a gel or colloidal mass. The molar mass given compound stibnite S b 2 S 3 is 339.7 g / m o l. The mass percent of antimony in S b 2 S 3 can be calculated as follows, Molar … Molar Mass = Mass of the Substance (Kg)/Amount of Substance (Mol) Mole or mol is the unit used to measure the amount of a substance. This converts atomic units to grams per mole, making the molar mass of hydrogen 1.007 grams per mole, of carbon 12.0107 grams per mole, of oxygen 15.9994 grams per mole, and of chlorine 35.453 grams per mole.
