passage 1866
a sample of a substance has a mass of 3240 grams (g) and a volume of 360 cubic centimeters (cm³). what is this substance?
a. copper
b. gold
c. iron
d. lead
question 6.
a sample of a substance has a mass of 10,146 grams (g) and a volume of 890 cubic centimeters (cm³). what is this substance?
a. air (dry)
b. magnesium

Explanation:

Step1: Recall density formula

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

Step2: Calculate density of the substance

Given $m = 10146\ g$ and $V=890\ cm^{3}$, then $
ho=\frac{10146}{890}=11.4\ g/cm^{3}$.

Step3: Match with table

From the table, lead has a density in the range of $11.3 - 11.4\ g/cm^{3}$.

Answer:

D. lead
