CHAPTER 3 How to Calculate Present Values Answers to Practice Questions 1. a. PV = $100 0.905 = $90.50 b. PV = $100 0.295 = $29.50 c. PV = $100 0.035 = $ 3.50 d. PV = $100 0.893 = $89.30 PV = $100 0.797 = $79.70 PV = $100 0.712 = $71.20 PV = $89.30 + $79.70 + $71.20 = $240.20 2. a. PV = $100 4.279 = $427.90 b. PV = $100 4.580 = $458.00 c.

observed chemical reactions‚ the first step to determine the identity of an unknown is to purify the substance. One technique often used to purify solids is recrystallization from a selected solvent. Because of the variable solubility of different compounds in various solvents and at various temperatures‚ it is possible to remove impurities by dissolving the unknown and then immediately cooling the solvent. The unknown recrystallizes‚ but the impurities remain dissolved in the solvent. It is then

The Population Size of Multiple Microorganisms in Aerobic Compost Alison Pagano‚ Lauren Sammaritano Biology IV- Ecology 4-11-13 Abstract. The experiment provided evidence of microorganisms in aerobic compost. 18 buckets were set up with three different trials of compost‚ wet‚ dry‚ and moist. Although microorganisms were present they were too small to be identified and also conditions in the experiment were not stable enough to maintain life. Due to this we were not able to make

Introduction Percentage composition is the percentage of a formula mass represented by each element. Percentage composition compares the mass of one part of a substance to the mass of the whole. The law of definite proportions states that a specific compound always contains the same amount of elements in fixed proportions by mass. By finding the percent composition of magnesium oxide one will essentially be proving this law to be true. Purpose The purpose of this lab is to determine the percent composition

Melissa Benning Introduction The purpose of the coordination complex lab is to determine the absorbance spectra of complexes based on their color. Every complex has its own color which results from the wavelengths of white light it reflects. The complexes will be compared by the color each reflects and by the energy of the waves each absorbs. The purity of the synthesized complex will also be found. Procedure Part I: Preparation of the Complex A sample of copper sulfate pentahydrate (6.285g)
