Lab

Density Lab Introduction: meanness is a precise most-valuable characteristic of all substances and it can be utilise to draw any substance. To generate the assiduousness, first fate to check 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 domiciliate and mea positive(predicate) it reveal. Once you have all this information divide the down/volume. Purpose: The purpose of the density lab is to find the density of both tied(p) and irregular shaped objects and liquids. Materials: ·Triple transfer balance ·Graduated cylinder ·3 regular coat objects ·Ruler ·Aluminum cylinder ·Water · computer outgrowth: Part I: 1.To find the volume of a regular shaped object you need to measure the length, width, and height of separatel y object. Use cm. 2.To calculate the volume function 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 to each one object. Be sure to commemorate 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 smokestack 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 troika: ! 1.Calculate the percent error of liquid A % Error= demonstrable measure Experimental value x 100% substantial 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 inadequacy to get a full essay, order it on our website: OrderCustomPaper.com
