correlauoh ul ila3s an Ulu Software A student is asked to identify a solid by determining its density. The student measured the mass of the solid by weighing an empty beaker (mass 46.2421 grams) and placing the solid in it (mass of beaker+solid 74.4568 grams). The student placed the solid in a graduated cylinder containing 37.45 mL of water. The level of water rose to 46.78 mL when it contained the solid. Determine the density of the solid. Show all your calculations to the correct number of significant figures. PROCEDURE A. USE OF A PIPET t nu Mill practira the handling of a 10 mL pipet. The pipet should be perfecty clean at the beginning of

Explanation / Answer

Mass of beaker =46.2421 g

Mass of beaker + solid =74.4568 g

Mass of solid = 74.4568 - 46.2421 = 28.2147 g

Volume of water before adding solid = 37.45 mL

Volume of water after adding solid = 46.78 mL

Volume water raised = 46.78 - 37.45 = 9.33 mL = volume of solid

Density = mass/ volume

Plugin the value and solve for density

Density =28.2147 g/9.33 mL

=3.02 g/mL

Density of solid = 3.02 g/mL
