For which object does the method of volume by displacement give an inaccurate result? Why?
A4. Calculate the density of each object (use the volume by displacement determination of the volume for
each object except the wooden sphere; for the wooden sphere use the volume calculated from the
diameter). Show all work with units and record your answers in the table below to the correct number
of significant figures and with proper units. pensitty=MassOF Substance
