A2.50 gram rectangular object has measurements of 22.0 mm, 13.5 mm, and 12.5 mm. what is the object’s density in units of g/ml? use significant figures. do not enter “g/ml” as part of your answer. do not use scientific notation.

Density is equal to the ratio of mass to the volume.

Mathematical expression is given by:

    (1)

Mass of the rectangular object  = 2.50 g

Volume  =

= 3712.5

Now, convert into mL

1 = 0.001 mL

Thus, volume  =  3.7125 mL

Put the values in formula (1)

= 0.6734 g/mL

In three significant figures, density is equal to 0.673 g/mL

Hence, density is equal to 0.673 g/mL

answer: c.
