How do you find the molarity of a solution
WebDec 9, 2024 · Step 1: Determine Moles of Solute The first step in calculating molarity is to determine the number of moles in four grams of solute (sucrose) by finding the atomic mass of each atom in the solution. This can be done using the periodic table. The chemical formula for sucrose is C 12 H 22 O 11: 12 carbon, 22 hydrogen, and 11 oxygen. WebNov 8, 2024 · Calculate Molarity: moles solute per liter of solution ( not volume of solvent added since the solute takes up some space) symbol: M M = moles / liter Example: What is the molarity of a solution of 6 grams of NaCl (~1 teaspoon of table salt) dissolved in 500 milliliters of water? First, convert grams of NaCl to moles of NaCl.
