If the mass of a material is 45 grams and the volume of the material is 8 cm^3, what would the density of the material be?name the answer and the unit because i need both you. and no guessing.

The density of the substance is the ratio of its mass over the space it occupies. In mathematical equation, this can be expressed as,

        ρ = m / v

where ρ is density, m is mass, and v is volume. 

Substituting the known values from the given,
 
    ρ = (45 g) / (8 cm³)

     ρ = 5.625 g/cm³

ANSWER: 5.625 g/cm³

The answer is a 0.64 volts
