Solutions Molarity Worksheet Name: _____KEY_____ 1. When we dissolve a cube of sugar in one cup of water, we create a homogeneous mixture. Such mixture is called a solution. The sugar is the solute and water is the solvent. 2. The molarity of a solutio n is defined as the moles of solute per liter of solution. Molarity is abbreviated as M. When the solvent is water, we have …
