2. A student needs to determine the density of two metal objects. The first object is a cube and the second object is a rectangular bar. The student uses calipers to measure the length of the objects. a. What is the density (in grams per milliliter) of the metal cube if it has a mass of 84.55 g and an edge length of 2.16 cm? mL b. What is the density (in grams per milliliter) of the rectangular bar if...

A student needs to determine the density of an irregularly shaped object. This student prepares a solution mixture where the object is suspended. The collected data is shown in the table below. Liquid g Density mL Volume (mL) Chloroform 1.465 7.81 Ethanol 0.789 2.53 Determine the density of the object. Object's density = 1.300 mL
You have two objects made of the same substance. Object 1 is a cube with a mass of 465.5 g. You measure the side of the cube using a ruler and find it to be 3.17 cm. Object 2 is a sphere with a mass of 232.8 g. You find the volume of the sphere using water displacement. The volume of the water in a graduated cylinder initially is 120.0 mL, and when the sphere is added the new volume...
A student needs 15.0 grams of ethanol for an experiment. If the density of ethanol is 0.789 g/mL, how many milliliters of ethanol are needed? (use numbers only and do not include units)
Ana lab a student determines the density of a metal object by measuring its mass on a balance and its volume by displacement in a graduated cylinder In the lab, a student determines the density of a metal object by measuring its mass on a balance and its volume by displacement in a graduated cylinder. The data collected by the student is shown. mass of object: 46.675 g volume of water in cylinder before object submersed: 29.79 mL volume of...
In the lab, a student determines the density of a metal object by measuring its mass on a balance and its volume by displacement in a graduated cylinder. The data collected by the student is shown. mass of object: 42.231 g volume of water in cylinder before object submersed: 28.01 mL volume of water + object in cylinder: 34.39 mL Calculate the density of the object. d = g/mL Based on the recorded volume data, and assuming that the student...
