    I.Introduction Hydatidiform mole is a tumor that forms in the uterus as a mass of cystsresembling a bunch of grapes. Hydatidiform moles occur during the childbearing years‚ and they do not spread outside the uterus. However‚ a malignancy called choriocarcinoma may start from a hydatidiform mole. In its early stages‚ a hydatidiform mole may look like a normal pregnancy. Diagnosis is based on a history of lack of fetal movement‚ a pelvic examination‚ an ultrasound‚ and a blood test

    normal pregnancy progress into a pathological one. It is characterized by the presence of a hydatidiform mole‚ which the chorionic villi around the fetus degenerate and form clusters of fluid-filled sacs‚ resulting in tumor growth that forms in the uterus as a bunch of cysts resembling grape-like vesicles that are visible to the naked eye. Hydatidiform mole (also known as hydatid mole or mola hydatidosa) is type a gestational trophoblastic disease that results from over-production of the tissue

    I. INTRODUCTION Hydatidiform Mole (H-mole or Gestational trophoblastic disease) is abnormal proliferation and then degeneration of the trophoblastic villi (Garg & Giuntoli‚ 2007). As the cells degenerate‚ they become filled with fluid and appear as clear fluid-filled‚ grape-sized vesicles. The embryo fails to develop beyond a primitive start. Abnormal trophoblast cells must be identified because they are associated with choriocarcinoma‚ a rapidly metastasizing malignancy. (Pillitteri‚ 2010)

    Reactions Objective In this lab we took Fe(NO3)3 and NaOH and mixed 7 different mole ratios in graduated cylinders to determine what the mole ratio is. We also did the same thing with solutions of CuCl2 and Na3PO4. We determine the mole ratios by graphing the volume of reactant #1 vs. volume of precipitate for each reaction. Data Part 1.)

    Convert from grams to moles using molar mass. To get moles from grams of potassium chlorate (KClO3): [molar mass = 122.55 g/mol] 138.6 g KClO3 X ( 1 mol / 122.55 g ) = 1.131 mol KClO3 3. Determine the limiting reagent [if necessary] (Use mole ratios to figure out.) * Not necessary to determine because there is only 1 reactant in this decomposition reaction. 4. Use ratios to find the moles of the reactant or product
