Question

question 1-4
the weight of gold jewelry can vary depending on the style, size, and the type of gold its made from. a 5.0 g nugget of pure gold has a density of 19.3 g/cm3. your friend purchased his girlfriend a bracelet made of 3 grams of pure gold.
density = \\( \frac { mass } { volume } \\)
what is the density of the bracelet?
19.3 g/cm3
1.66 g/cm3
20.5 g/cm3
0.60 g/cm3

Explanation:

Step1: Identify the formula

Density formula is \( \text{Density}=\frac{\text{Mass}}{\text{Volume}} \). Given mass \( m = 5.0\ g \) and density \(
ho=19.3\ g/cm^{3} \) (from the gold nugget, as density is a characteristic property of a pure substance).

Step2: Recall the property of density

Since the bracelet is made of pure gold (same substance as the nugget), the density of the bracelet is the same as the density of the gold nugget.

Answer:

\(19.3\ g/cm^{3}\) (corresponding to the fourth option in the given choices)
