Question

use the table below to answer the following questions:

substance	density at 20 °c	substance	density at 20 °c
corn oil	0.92 g/cm³	corn syrup	1.38 g/cm³
water	1.00 g/cm³	copper	8.80 g/cm³

an object with a mass of 24g and a volume of 32ml is most likely what substance?
copper
wood
rubber
corn oil

Explanation:

Step1: Recall density formula

The density formula is $
ho=\frac{m}{V}$, where $
ho$ is density, $m$ is mass and $V$ is volume.

Step2: Convert volume unit

Since $1\ mL = 1\ cm^{3}$, the volume $V = 32\ mL=32\ cm^{3}$, and the mass $m = 24\ g$.

Step3: Calculate density

Substitute $m = 24\ g$ and $V = 32\ cm^{3}$ into the density formula: $
ho=\frac{24\ g}{32\ cm^{3}} = 0.75\ g/cm^{3}$.

Step4: Compare with given densities

Compare the calculated density $0.75\ g/cm^{3}$ with the densities in the table. The density of wood is $0.70\ g/cm^{3}$, which is closest to the calculated density.

Answer:

wood
