Question

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 water + object in cylinder: 35.37 mL Calculate the density of the object. g/mL Based on the recorded volume data, and assuming that the student used correct lab technique, what volume corresponds to the separation between two calibration lines on the graduated cylinder? 0.001 mL 1 ml O 0.01 ml O 0.1 ml

Answer 1

Density = mass of object/volume of object

mass of object = 46.675 g

Volume of object = (Volume of water + object in cylinder) - (Volume of water in cylinder before object submersed)

Volume of object = 35.37 mL - 29.79 mL

Volume of object = 5.58 mL

Density =

46.675g 5,58mL

Density = 8.36 g/mL

# The Separation between two calibration lines on the graduated cylinder is 0.01 mL.

Because the volume recorded my student is upto 2^nd decimal place.
