Test Tube #2: Unknown sample (KCLO3 + KCL) 1. Determine the weight of unknown heated. 2. Determine the weight of oxygen gas released using the constant weight obtained after completion of the heating's. 3. Determine the number of oxygen gas (0₂) lost? 4. Using stoichiometry, use the number of O₂ gas released to determine the moles of KCLO decomposed, 5. Determine the number of grams of KCLO, decomposed. 6. Based on the number of grams of KCLO, decomposed and the total amount of unknown placed in the test tube, determine the percent KCLO, present within the unknown.
