    • 2 Pages

    This experiment will allow us to determine the molar mass of the unknown solute through calculating the difference in freezing point of the pure solvent and the solution with the unknown solute. This lab will show case one of the colligative properties of a solution. This property is dependent upon the number of solute molecules or ions and not the identity or chemical property of the solute.

    The second one is utilizing 65 Zn to analysis the removal of zinc in two different types of environment, mangrove-vegetated forest, and unvegetated tidal creek. In this study, sediments from a mangrove ecosystem in Sepetiba Bay was utilized for investigation since Zinc is the major contaminant in this region. In the laboratory, researchers used radiotracer 65Zn with half-life 244 days to undergo the experiment. Among the isotope of zinc, 65Zn has the longest half-life. Since it is the first time…
