Gold Density Analysis

Is the bracelet made of pure gold?

Given that pure gold has a density of 19.3 g/ml, a gold bracelet has a mass of 412 g and a volume of 22.4ml.

Answer:

No, the bracelet is not made of pure gold because the densities do not match.

First, let's calculate the density of the gold bracelet using the formula for density, which is mass divided by volume.

Given data:

Mass of the bracelet = 412 g

Volume of the bracelet = 22.4 ml

Using the formula:

d = mass / volume

Substitute the values:

d = 412 g / 22.4 ml

Calculate the density:

d ≈ 18.39 g/ml

The density of the bracelet is approximately 18.39 g/ml, which is lower than the density of pure gold (19.3 g/ml).

Therefore, based on the calculated density, the bracelet is not made of pure gold as its density does not match that of pure gold.
