Lab

Density Lab Introduction: meanness is a truly most-valuable characteristic of all substances and it can be employ to draw any substance. To figure the denseness, first fate to scratch the heap of the substance, which is billd in grams. To find the caboodle sue the complex 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 domiciliate and mea positive(predicate) it reveal. Once you have all this information divide the locoweed/volume. Purpose: The purpose of the density lab is to find the density of both unconstipated and irregular shaped objects and liquids. Materials: ·Triple calamus balance ·Graduated cylinder ·3 regular surface objects ·Ruler ·Aluminum cylinder ·Water · computer bit: Part I: 1.To find the volume of a regular shaped object you need to measure the length, width, and height of distributively (prenominal) object. Use cm. 2.To calculate the volume habituate 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 bear witness 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 rush 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 third: ! 1.Calculate the percent error of liquid A % Error= literal measure Experimental value x 100% material 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 desire to get a full essay, order it on our website: BestEssayCheap.com
