Question

A block of aluminum occupies a volume of 10 mL and weighs 50 g. What is its density?

a) 2 g/mL
b) 5 g/mL
c) 10 g/mL
d) 20 g/mL

Answer 1

The density of the given aluminum block is calculated by dividing the mass of the block (50 g) by its volume (10 mL), resulting in a density of 5 g/mL.

Step-by-step explanation:

To calculate the density of a block of aluminum, we use the formula: density = mass/volume. Given that the mass of the block is 50 g and the volume is 10 mL (or 10 cm³), we simply divide the mass by the volume.

So the density is calculated as follows:

Density = Mass / Volume

Density = 50 g / 10 mL

Density = 5 g/mL

Using the reference information, if one cubic centimeter of aluminum has a mass of 2.70 grams, then the density of aluminum is 2.70 g/cm³. However, in this specific exercise, the provided mass and volume of the aluminum block give us a density of 5 g/mL, which corresponds to answer choice (b).
