After heating to drive off all the water the mass is 2.790 g. What is the mass percent of MgCO3·3H2O in the mixture? a. 22.4% b. 43.2% c. 67.0% d. 77.6% e. 91.3% ____ 10. The combustion of 0.1703 mole of a hydrocarbon produces 12.27 g H2O and 22.48 g CO2. What is the molar mass of the hydrocarbon? Molar Mass is the mass of one mole of a substance (6.02 x 1023 formula units). The molar mass is calculated by taking the sum of the atomic weights of all the atoms which form the molecule. First determine the number of each atom in the formula.Jan 27, 2018 · Here is how to convert a g/100mL value to molar solubility: 1) multiply the g/100mL value by 10/10. This converts it to grams per 1000 mL or, better yet, grams per liter. (Sometimes the data is given in g/L. When that happens, this step is skipped.) 2) divide the grams per liter value by the molar mass of the substance.

A 3.585-g sample of the powder was dissolved in HNO3 and heated to convert all iron to Fe3 . The addition of NH3 precipitated Fe2O3·xH2O which was subsequently ignited to produce 0.350 g of Fe2O3. What was the mass of FeSO4·7H2O in the 3.585-g sample? Name: Lead (II) Bromide. Alias: Plumbous Bromide. Formula: PbBr2. Molar Mass: 367.008. Example Reactions: In chemistry, the molar mass M is a physical property. It is defined as the mass of a given substance divided by its amount of substance. The base SI unit for molar mass is kg/mol. However, for historical reasons, molar masses are almost always expressed in g/mol.Molar mass is the mass of one mole of a substance. Molar mass is reported in grams per mole or g/mol. The molar mass of water is 18.02 g/mol. You'll note that this is the same number you got for the molecular weight, but the units are different.The molar mass of a substance is the mass in grams of 1 mole of the substance. As shown in this video, we can obtain a substance's molar mass by summing the molar masses of its component atoms.
