Final answer:
The mass of a box with a density of 3.9 g/mL and a volume of 2.5 cm³ is 9.75 grams, determined by the formula Mass = Density x Volume.
Step-by-step explanation:
To determine the mass of a box, one can employ the formula Mass = Density x Volume. In this scenario, where the box possesses a density of 3.9 g/mL and a volume of 2.5 cm^3, the substitution of these values into the formula yields Mass = 3.9 g/mL x 2.5 cm³.
The resulting calculation, Mass = 9.75 g, reveals that the mass of the box is 9.75 grams. This computation is grounded in the fundamental relationship between mass, density, and volume, where density represents the amount of mass per unit volume.
By multiplying the density of the substance by its volume, one obtains the mass, a crucial metric in various scientific and practical applications, ranging from material science to everyday measurements in fields such as chemistry and physics.
