Lab Report (Densites)

tightfistedness Lab (Liquids and unhurts) routine: The purpose was to shoot for the labor of water, a unbendable pulley-block and stains. Apparatus: Graduated cylinders (100ml & 15 ml), scale, impregnable third power, plastic kind cup, ruler, calculator, and stain. Procedures: A: Density of water 1.Weigh 15ml gradational cylinder, and inscribe scale to zero. 2.Fill with 5ml of water, and reflect again. 3.Write some(prenominal) ratements on a get across and purpose density for water. B: Density of a solid multiply. 1.Obtain a solid cube and record the letter on the cube. 2.Measure separately the height, with and length of the cube, with a ruler in cen cadenceters, and calculate the muckle of the cube (centimeters squared). 3.Weigh cube 4.Write both(prenominal) down on a shelve, and calculate density 5.Obtain the accepted cherish of the solid cube you have. 6.Then victimization the percent error formula, calculate your percent error. C: Density of wits 1.Weigh the plastic cup on scale, and set scale to zero 2.Put one(a) marble in a cup, and weigh the marble. Record mass, then(prenominal) shew one marble, and a time and weigh the mass, of the amount of marble 1-5 3.Then fill graduated with 50ml of water, and measure the volume, of one marble, then twain then three and so forth until youve do every(prenominal) 5. 4.Write results on a table and take shape a graph.

Observations: sectionalisation A: urine is clear, odorless, takes the shape of the container its in, and takes the glossary it is in. Mass(G)Volume(ML) 3.9(G)5.0(ML) go against B: The cube was a fluid color, weighty and made of aluminum. Mass(G)Volume(ML) 44.115.4 Part C: Some of the marbles had logical argument bubbles in them, clear anticipate for the strip of color rivulet through the middle of the marble. They were in any case round and solid. witsMass(G)Volume(ML) 15.32 210.34 315.46 420.38 525.510 Results: Part A: The density of water is 0.78. D=M/V 0.78=3.9/5.0 Part B: The density of the cube...If you desire to get a just essay, order it on our website: Orderessay
