Final answer:
The density of an object with a mass of 4.0 g and a volume of 39.0 cubic centimeters is approximately 0.1026 g/cm³.
Step-by-step explanation:
To calculate the density of an object, you divide the mass of the object by its volume. In your case, the mass is given as 4.0 g and the volume is 39.0 cubic centimeters. Applying the formula for density (density = mass/volume), we have:
Density = Mass / Volume
Density = 4.0 g / 39.0 cm³
Density = 0.1026 g/cm³ (approximately)
The density of the object is therefore approximately 0.1026 grams per cubic centimeter.
