Roland is measuring a physical property of an object. he records the measurements: 3.12g/cm^3. roland was most likely measuring which of the following:
a. volume
b. weight
c. density
d. mass

Answer:   C. Density

Roland was most probably measuring density.

Explanation:

The measurement given in the question is . In The unit of the measurement g is the unit of mass and is the unit of volume. Ratio of mass to volume gives an object’s density.

Hence is the unit of density. Density has other units as well.  

Density of liquids is a crucial factor in fluid mechanics. Difference in densities of an object and a fluid determines whether that object will float or sink in that liquid. When two different liquids are mixed the liquid which has lesser density will form a layer above the denser liquid.
