Question

Which measurement, in grams per cubic centimeter, is closest to the density of air, which is approximately 0.001293 grams per cubic centimeter?

A) 0.0001 g/cm³
B) 0.001 g/cm³
C) 0.01 g/cm³
D) 0.1 g/cm³

Answer 1

The measurement closest to the density of air, which is approximately 0.001293 g/cm³, is 0.001 g/cm³, corresponding to option B.

Step-by-step explanation:

The density of air is approximately 0.001293 grams per cubic centimeter (g/cm³). When looking at the options provided:
A) 0.0001 g/cm³
B) 0.001 g/cm³
C) 0.01 g/cm³
D) 0.1 g/cm³
the measurement that is closest to the density of air would be option B) 0.001 g/cm³.

Density is a measurement that compares the mass per unit volume of a substance. For example, if we have a block of material with a mass of 300 grams and a volume of 100 cm³, its density would be 3 g/cm³. Materials can have a wide range of densities; for instance, plastic insulating foam has a density of less than 0.1 g/cm³, while gold has a density of approximately 19.3 g/cm³.
