Chemistry Quiz On Molarity! Trivia

Questions: 10 | Attempts: 669 | Last updated: Mar 22, 2025

Sample Question
How do you prepare a .3 M solution of NaCl? The molar mass of NaCl is 22.99 + 35.45. Since a .3 M solution is required, multiply the molar mass by .3. Water is added to the 1-liter mark. REMEMBER: Molarity is Moles per Liter solution. The liter solution INCLUDES the water AND the salt -- salt has volume -- so it will be less than 1 Liter of water.

Find the molar mass of NaCl. Add that amount of NaCl to a volumetric flask and add distilled water to the 1 L mark. Stir.

Find the molar mass of NaCl. Add that amount of NaCl to a volumetric flask and add 1 Liter of distilled water. Stir.

Look up the molar mass of sodium and chlorine on the periodic table. Multiply the molar mass by .3. Place this amount in a volumetric flask and add distilled water to the 1 L mark. Stir.
