Answer:
Density of the rock = 2.82436 g/cm³
Explanation:
We are given that:
[tex]density = \frac{mass}{volume}[/tex]
We are also given that:
mass of rock = 8 grams
volume of rock = 2.8325 cm³
Substitute with the given values in the equation to get the density as follows:
[tex]Density = \frac{8}{2.8325} = 2.82436[/tex] g/cm³
Hope this helps :)
Answer:
2824.36011 kg/m³
Explanation:
The missing statement is: determine the rocks density in kg/m³
- Data
mass of the rock, m = 8 g
volume of the rock, V = 2.8325 cm³
- Unit conversions
1000 g are equivalent to 1 kg, then 8 g are equivalent to:
1000 g / 8 g = 1 kg / x kg
x = 8/1000 = 0.008 kg
1,000,000 cm³ are equivalent to 1 m³, then 2.8325 cm³ are equivalent to:
1,000,000 cm³ / 2.8325 cm³ = 1 m³ / x m³
x = 2.8325/1,000,000 = 0.0000028325 m³
- Density calculation
Density = m/V
Density = 0.008/0.0000028325
Density = 2824.36011 kg/m³
