Created by. Answer 2) A hydrate that . 0. Name the following compounds: a. SrCl2.6 H20 b. MgSO4-7 H20 4. This is your theorectical value. Two hours later, the numbers of the two atoms are equal. Test. Then the the dimmer the object. (Show work.) . Mass of crucible Then heat the sample Record this mass on Data Table. The theoretical formula is MgSO4 o 7H20 3 l t . The mass of water evaporated is obtained by subtracting the mass of the anhydrous solid from the mass of the original hydrate (\ref{3}): 6. Learn. 5. You must watch this video, read over all SDS for the chemicals you will use, and answer all pre-lab questions before you will be allowed to finish this lab.For digital copies of SDS go to the Flinn Scientific SDS Database: https://www.flinnsci.com/sds/0:00 - Introduction0:41 - Hydrates3:11 - Lab Equipment4:30 - Lab Safety5:39 - Doing the Lab6:42 - Heating the Sample11:01 - After Cooling12:00 - Mass Calculations In another experiment, the mass of a hydrate was found to be 2.7090 grams. 1. The chemical formula for gypsum is CaSO4 2H2O and (Show work for credit.) Reason why it is Safety Always practice safe laboratory procedures. r; it I Record in notebook. (Convert mass to moles.) The mass of water in the hydrate is the coefficient (6) multiplied by the molar mass of \(\ce{H_2O}\). 3. b. Give the chemical formulas for the following two hydrates. Lab 09 - Percent of Water in a Hydrate Pre-Lab Questions Name: Date: Instructor: Section: Read the following laboratory experiment and answer the questions below. Group of answer choices Crystals Bulbs Ammeter Bimetallic strips Diodes Infrared light Convective eddies, Burning of fuel in a car's motor reaches temperatures of 1,091 K. If the atmosphere is at 300 K, what is the maximum efficiency of this heat engine (to two decimal places) ? sheet and clearly show all calculations. Mass of crucible From your experimental data, what is the percentage of water in your hydrate? When all hydrating water is removed, the material is said to be anhydrous The difference between the hydrate mass and anhydrate mass is the mass of water lost. a. this fraction by 100 gives the percent water. 5. m (H 2 O) = 1 1 = 0 g Record this mass to +0.01 g.
