Lab

Density Lab Introduction: meanness is a really most-valuable characteristic of all substances and it can be occasion to draw any substance. To kick downstairs the assiduousness, first fate to take chances the heap of the substance, which is billd in grams. To find the caboodle sue the conglomerate air balance. Then find the volume of the substance by multiplying length * width* flower or if the substance is a liquid sue a graduated piston sleeping room and mea positive(predicate) it reveal. Once you have all this information divide the pack/volume. Purpose: The purpose of the density lab is to find the density of both rule-governed and irregular shaped objects and liquids. Materials: ·Triple re balance ·Graduated cylinder ·3 regular surface objects ·Ruler ·Aluminum cylinder ·Water · computer number: Part I: 1.To find the volume of a regular shaped object you need to measure the length, width, and heig ht of individually object. Use cm. 2.To calculate the volume use the formula V =L x W x H 3.To find the volume of the irregular shaped object you need to use water displacement for separately object. Be sure to register the bottom of the meniscus. V of object = (V of water+Obj)-(v of water) 4. replicate for each of the 3 solid objects. 5.Calculate the density D= M/V Part II: 1.Find the view of a dry 10 mL graduated cylinder 2.Measure out exactly 10 ml of water 3.Mass the graduated cylinder with water 4.Calculate the mass of water 5.

Find the density of water Part collar: ! 1.Calculate the percent error of liquid A % Error= demonstrable measure Experimental value x 100% unquestionable Value Results: #17 L-10.5 cm Density- .843 g/cm W-1.3 cm Mass- 59.85 g H- 5.2 cm Vol.- 7.98 cm squared # 26 L- 6.9 cm Density- 1.38 g/cm W-2.5 cm Mass- 99.9 g H-4.2 cm Vol.- 72.4 cm squared #28 L- 8.1 cm Density- 1.27 g/cm W-...If you pauperism to get a full essay, order it on our website: BestEssayCheap.com
