Question

A 2.98 gram rectangular object has measurements of 21.1 mm, 14.2 mm, and 12.1 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.

Answer 1

Answer:

density = 0.822  g/mL

Explanation:

We calculate the density knowing the flowing formula:

density = mass / volume

mass = 2.98 grams

volume = 21.1 × 14.2 × 12.1 = 3625 mm³ = 3.625 cm³ = 3.625 mL

density = 2.98 / 3.625 = 0.822  g/mL
