Question

use the formula
calculate the missing value using the two given values!
table with columns: mass, volume, density; rows: textbook (2,000 g, 4,000 cm³, missing), apple (100 g, missing, 0.8 g/ml), football (missing, 625 ml, 0.64 g/ml), gold bar (16,000 g, 800 cm³, missing), can of soup (150 g, missing, 0.75 g/cm³)
think about it
whats more likely: an object whose mass is 0, or an object whose weight is 0?

Explanation:

TEXTBOOK (Find Density)

Step1: Recall density formula

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

Step2: Substitute values

Given $m = 2000\ g$, $V = 4000\ cm^3$. Substitute into formula: $
ho=\frac{2000}{4000}$

Step3: Calculate

$\frac{2000}{4000}=0.5\ g/cm^3$

APPLE (Find Volume)

Step1: Rearrange density formula

From $
ho = \frac{m}{V}$, we get $V=\frac{m}{
ho}$.

Step2: Substitute values

Given $m = 100\ g$, $
ho = 0.8\ g/mL$. Substitute: $V=\frac{100}{0.8}$

Step3: Calculate

$\frac{100}{0.8}=125\ mL$

FOOTBALL (Find Mass)

Step1: Rearrange density formula

From $
ho = \frac{m}{V}$, we get $m=
ho\times V$.

Step2: Substitute values

Given $
ho = 0.64\ g/mL$, $V = 625\ mL$. Substitute: $m = 0.64\times625$

Step3: Calculate

$0.64\times625 = 400\ g$

GOLD BAR (Find Density)

Answer:

An object whose weight is 0 is more likely.

Final Answers for Table:

• TEXTBOOK Density: $0.5\ g/cm^3$
• APPLE Volume: $125\ mL$
• FOOTBALL Mass: $400\ g$
• GOLD BAR Density: $20\ g/cm^3$
• CAN OF SOUP Volume: $200\ cm^3$
• Think About It: An object whose weight is 0 is more likely.
