1) In table #4 main scale reading and Vernier coincidence are base measures whereas height of cylinder and main height are derived measurements.
In table #5 volume and mass are base measure and density is derived measurement. Density is mass per unit volume.(or mass divided by volume)
2) given density marble= 2.65 g/cm^3 = it must be made of primarily limestone(density=2.7 g/cm^3) with few other additives .
cylinder=1.25 g/cm^3= cylinder might be made of polycarbonate(1.3 g/cm3) or some kind of hard rubber(1.2g/cm3).
Please let me know if it was helpful. Thank you!

Find the densities with error:
Calculate the volumes, V, and V2, and densities, ρ, and f, required in the tables below. You need to determine the correct uncertainty, e.g. AL, for each instrument. Check with your instructor. Also, read the Introduction in this experimental procedure.

4. Suppose that a student performed the experiment and calculations perfectly as directed except that, unknown to the student, the balance was not zeroed but weighed 0.100 g too high throughout the experiment. Would the calculated val- ue for the density of the unknown liquid be correct? That is, would it be equal to, higher than, or lower than the true value.
