Question

The mass of the quartz crystal shown below is 10 grams, and its volume is 4 cm3. What is the density of quartz?

a. 3.5 g/cm3
b. 2.5 g/cm3
c. 2.0 g/cm3
d. 3.0 g/cm3

Answer 1

`{\boxed{\text{b. 2.5 g/cm}^(3)}}`

Step-by-step explanation:

`\text{Density} = (m)/(V) = \frac{\text{mass}}{\text{volume}}`

Data:

m = 10 g

V = 4 cm³

Calculation:

`\text{Density} = \frac{\text{10 g}}{\text{4 cm}^(3)} = \textbf{2.5 g/cm}^(3)\\\text{The density of the crystal is ${\boxed{\textbf{2.5 g/cm}^(3)}}$}`
