DIETARY CusO4.5 Heo B. Prepare the Data Section Prepare the Data Section of the notebook. Format this section for the collection of data and observations during the lab, as shown on the next page of this Lab Manual. The Data Section must be formatted before coming to lab. II. Data Copy the following format and table into your lab notebook. Collect data as described in the Procedure Section. Assigned hydrate (record the formula using "x" for the waters of hydration) euso4 X H0 Appearance of the hydrate before heating Mass of empty crucible (g) Mass of crucible and hydrated salt (g) Mass of crucible and salt after 1st heating (g) 17/2.90 Mass of crucible and salt after 2nd heating (g) Mass of crucible and salt after 3rd heating (g) 16,9299 III. Calculations Begin calculations on the next page after the Data Section in your laboratory notebook; copy the following table to summarize the results of your calculations. You must show a sample of each calculation performed below the table. Label all results clearly and include units. Mass of hydrated compound (g) 1.9309 l2, B071,9703-2.2319 =0,804 0.008 965 Mass of anhydrous compound (g) Mass of water (g) Moles of anhydrous compound (mol) $968900= Moles of water (mol) O:045 d,804% i8.01 5289F 0,07762878 Empirical formula for the hydrate (calculated) Empirical formula for the hydrate (TA provided) uS04 SH20 Theoretical mass of anhydrous compound (g) error To determine the last two entries of this table: Based on the formula of your assigned hydrate (provided by your TA), find the theoretical mass percent of the anhydrous compound in the hydrate. Then determine the mass of anhydrous compound that is theoretically present in your initial sample of hydrate. This is the theoretical amount that should be obtained after heating. Determine a percent error based on the measured experimental mass of anhydrous compound. 53 Lab 3 - Gravimetric Analysis of a Hydrate Date
