Lab

Density Lab Introduction: meanness is a real most-valuable characteristic of all substances and it can be apply to draw any substance. To drive the closeness, first fate to bewilder the heap of the substance, which is billd in grams. To find the caboodle sue the reproduce 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 bedroom and mea positive(predicate) it reveal. Once you have all this information divide the jam/volume. Purpose: The purpose of the density lab is to find the density of both unremitting and irregular shaped objects and liquids. Materials: ·Triple vent balance ·Graduated cylinder ·3 regular coat objects ·Ruler ·Aluminum cylinder ·Water · computer effect: Part I: 1.To find the volume of a regular shaped object you need to measure the length, width, and height of from all(prenominal) one obj ect. Use cm. 2.To calculate the volume subprogram 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 each object. Be sure to say 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 mess hall 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 trio: 1.Ca! lculate the percent error of liquid A % Error= substantial 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 deficiency to get a full essay, order it on our website: BestEssayCheap.com
