The density of an object is defined as its mass divided by its volume. suppose the mass and volume of a rock are measured to be 8 g and 2.8325 cm3.

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

b.

hope this : )
