Practice: Calculate the molecular weight of C3H5N3O3.
Molar Mass is a physical property that represents the mass of a substance divided by the amount of that substance.
Concept #1: Calculating Molar Mass
The units for molar mass are in grams per mole.
Example #1: Calculate the molar mass of the compound (NH4)2SO4.
Practice: Calculate the molecular weight of C3H5N3O3.
Practice: The reaction between nickel metal and hydrochloric acid is not a simple dissolution. The product formed is NiCl2 • 6 H2O (s), nickel (II) chloride hexahydrate, which has exactly 6 waters of hydration in the crystal lattice for every nickel ion. What is the molar mass of nickel (II) chloride hexahydrate, NiCl2 • 6 H2O (s)?
Practice: What is the molar mass of diazepam also known as Valium if 0.05570 mol weighs 15.86 g?
