15. remove watch glass after ~1 min and continue heating for ~10mins (until all of the H₂O is driven off); record observations 5.) CHEM 102 Lab 2 Empirical Formula of a Hydrate Post-Lab Questions Each lab group is responsible for turning in a data table like that on page 7 along with answers to the following questions as a single Word file with everyone's names on it to Moodle by the beginning of our next lab. For example, CH 2 O is the empirical formula and C 6 H 12 O 6 is the molecular formula of the sugar glucose. Lab – Formula of a Hydrate - Help with calculations Magnesium sulfate ( MgSO 4) is a molecule that loves to hold on to water (hydrophilic). Sheet1. cover the evaporating dish w/hydrate in it with a watch glass and begin heating under a strong flame; record observations 4.) 2- di. 3-tri. mass the evaporating dish, hydrate + dish 2.) Question: Unit 2, Lab 2: Empirical Formula Of A Hydrate Name: Date: Experiment 1: Remove The Water Of Hydration From Copper Sulfate Hydrate Lab Results Record The Following Data In The Table Below. Digication ePortfolio :: General Chemistry (Alexander Antonopoulos) by Alexander P. Antonopoulos at Salve Regina University. 1.) Empirical Formula of a Hydrate- Guided Inquiry p. 3. Determining the empirical formula of a hydrate Download the Lab handout using this link : There is no presentation to go with the handout, but on the handout is another link to a simulation. had a formula of CoCl2(6H2O and that you had 1.80 moles of CoCl2, how many moles of H2O would be present? As the first step, use the percent composition to derive the compound™s empirical formula. What is the name of CoCl2(6H2O? To determine the percentage of water in a hydrate. Empirical Formula Determination Pre Lab The Empirical Formula is the simplest formula that may be written. Take the mass of the hydrate and subtract the mass of the anhydrate to get the mass of water. PROCEDURE: When copper (II) sulfate hydrate, a blue crystalline solid containing embedded water molecules (called a hydrate), is heated in air, it loses the water molecules and the blue solid is transformed to a white anhydrous (no water) crystal known as copper (II) sulfate. 16. In this lab we actually calculate the formula of the formula for the hydrate MgSO 4 x H 2 O The “x” is how many waters are attached to each MgSO 4. Formula represents the actual number of atoms in a molecule. Each square in the data table is worth 2 points. 4-tetra. We have pre-lab questions we need to fill out, but i'm lost. Empirical Formula of a Hydrate Lab? 5-penta. 6-hexa-7-hepta Pre-lab problem: You weigh a crucible with cover and find that they weigh 19.12 grams. Download Ebook Determining Empirical Formula Lab Answers comparison of the compound™s empirical formula mass to its molar mass. observe the hydrate before heating 3.) Our lab is tomorrow and i have no idea what to do, my teacher isn't very good, ://. 1- mono. Lab #5 Determining Chemical Formula of a Hydrate Zeeshan Saleem Nikki Pandey Brandt Farazian Hoang Phan 6/15/2015 Chem 1411.S2L Abstract: The Purpose of this lab was to find the chemical formula for ZnSO 4 through determining the amount of anhydrate and hydrate. If you were told that your hydrate. Lab 2: Determine the Percentage of Water in a Hydrate: The goal of this experiment is to learn how to properly calculate the ratio of salt to water, in a hydrated salt, and to calculate the percentage of water (by mass) within a hydrated salt.
