How To Measure Loss Of Mass In A Reaction

The video tutorial explains the concept of mass conservation in chemical reactions, emphasizing that the total mass of reactants equals the mass of products. It discusses how mass can be lost when products escape as gas, using the example of Alka-Seltzer in water. The tutorial details how to measure this mass loss using electronic scales and how to calculate it using moles and molar mass. It stresses the importance of pre-experiment calculations to ensure accuracy and identify potential issues with reactants or equipment.

What is the molar mass of carbon dioxide, and how is it calculated?

Why is it important for chemists to perform calculations before conducting experiments?
