Answer:
8.6g/cm³ (BRASS)
Explanation:
Given the following :
Mass of object = 86g
Volume of object = 10cm³
The density of an object is calculated using the formula :
Density(g/cm³) = mass(g) / volume(cm³)
Inputting our values :
Density = 86g / 10cm³
Density = 8.6g/cm³
According to the table provided, the object which corresponds to having a density of 8.6g/cm³ is BRASS
