Lavoisier Lab Purpose-The purpose of the experiment seeks to prove whether Lavoisier was right about his hypothesis which states "matter was conserved-meaning it is never created or destroyed during a reaction" You will measure the mass of two compounds before and after a reaction and see if the mass stays the same.


 * Reactants || Mass (G) ||
 * Mass of empty beaker A || 47.73 g ||
 * Mass of compound in beaker A || .7526 g ||
 * Mass of empty beaker B || 46.58 g ||
 * Mass of compound in beaker B || 1.23 g ||
 * Total mass of comp. in beaker A+B || 1.9826 g ||
 * Mass of clean filter paper || 0.84 g ||

Total mass of compound before the reaction: 1.983 g Total mass of compound after the reaction: 1.851 g
 * Products || Mass (G) ||
 * Mass of beaker A&Filter with comp. || 49.32 g ||
 * Mass of compound recovered in beaker A || .741 G ||
 * Mass of beaker B and compound || 47.69 g ||
 * Mass of recovered comp. in beaker B || 1.11 g ||
 * Total mass of both A&B comp || 1.851 g ||

Conclusion: The total mass of compound before and after the reaction were similar to each other. The difference between the before and after reaction is 0.132 g.The percent error is 6.66. 1.9839- 1.851 g% 1.983 g* 100= 0.132 g %1.983 g *100= 0.067 g *100 = 6.66 percent error. The average value using three different values (1.851 g+ 3.1 g+ 2.64 g) is 2.539 g of total mass after the reaction.
