Measuring For The Loss Of Mass In A Reaction

The video explains the concept of mass conservation in chemical reactions, highlighting 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 an Alka-Seltzer tablet in water. The video details methods to measure mass loss, such as using electronic scales, and explains how to calculate mass loss using moles and molar mass. It emphasizes the importance of these calculations in ensuring experiment accuracy and identifying potential errors.
