A student finds another object that looks similar to the first
object. They weigh this second object and record the mass to
be 33.4.g They fill a graduated cylinder about halfway and
record the volume as 12.3mL. The student carefully drops the
object into the graduated cylinder and the water rises to a
volume of 21.7mL.

c) Is this second object, also pure gold? Justify your answer
with a calculation.

The object is not pure gold because it does not the same density as pure gold.

What is density?

The density of an object is defined as the ratio of the mass to the volume of an object. We know that the density could be used to characterize an object. This is why we refer to the density of the object as an intrinsic property of the object. Since the density of the object does not change. We could use the density to determine if the second object is gold or not.

Mass of the object = 33.4.g

Inital volume of the water= 12.3mL

Final volume of the water = 21.7mL

Volume of the object = 21.7mL - 12.3mL = 9.4 mL

Density of the object = 33.4.g / 9.4 mL = 3.55 g/mL

The object is not pure gold because it does not the same density as pure gold.
