Lab experiment 12 Percent of water in a hydrate The goal of Experiment 12 was to learn how to calculate the percent of water (by mass) in barium chloride and an unknown hydrate salt‚ as well as properly calculating the water of crystallization for the unknown hydrate salt. A hydrate salt is composed of anions (-) and cations (+) surrounded by a fixed number of water molecules‚ called water of crystallization. The hydrate decomposes upon heating and

have chosen is percentages. A percent is a fraction that has a denominator of 100. Finding the percent of a number‚ and finding the missing percent could be very useful in the profession that I have chosen. The profession that I would like to pursue is accounting. Using percentages is used in many ways in accounting. One way is to do a trend analysis. A trend analysis calculates the percentage change for one account over a period of time of two years or more. An example of this would be to do a trend

2013 Percent Yield of Calcium Carbonate Introduction: The purpose of this experiment is to examine the percent yield of a precipitate in a double displacement reaction. A solution of calcium citrate and sodium carbonate were mixed together‚ then the products were filtered out as so only the precipitate remained. The filtered paper was then dried and the mass of the precipitate in the experiment divided by the theoretical mass of the precipitate from the calculated gave the percent yield.

Percent Composition Report Hypothesis : By using seperation techniques properly‚ the 3 substance such as; water‚ sand‚ and salt can be seperated and the percent composition of each substance. Which will then be calculated theoritically and after comparison with the actual result‚ the accuracy of the 2 result can be found. Aim : The aim of this experiment is to compare the gravimetric result of the original mixture and the separated substance. The other objective is to calculate each percent
