Question

1. use the data in the table to calculate the density of each unknown substance, then use the density chart provided to determine the identity of each substance. you do not have to show all work for this table and units have already been provided.

mass (g)	volume (cm³)	density (g/cm³)	substance
108	40
475	250
680	1000

Explanation:

Step1: Recall density formula

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

Step2: Calculate density for first row

For $m = 171$ g and $V=15$ cm³, $
ho_1=\frac{171}{15}=11.4$ g/cm³.

Step3: Calculate density for second row

For $m = 108$ g and $V = 40$ cm³, $
ho_2=\frac{108}{40}=2.7$ g/cm³.

Step4: Calculate density for third row

For $m = 475$ g and $V=250$ cm³, $
ho_3=\frac{475}{250}=1.9$ g/cm³.

Step5: Calculate density for fourth row

For $m = 680$ g and $V = 1000$ cm³, $
ho_4=\frac{680}{1000}=0.68$ g/cm³.

Mass (g)	Volume (cm³)	Density (g/cm³)	Substance (not - determined in this response as density - chart is not provided)
108	40	2.7
475	250	1.9
680	1000	0.68

Answer:

Mass (g)	Volume (cm³)	Density (g/cm³)	Substance
108	40	2.7
475	250	1.9
680	1000	0.68
