Question

20
the images below show the masses and compositions of six cubes. the cubes each have a volume of 1 cm³
using the formula d = m/v, which of the following has the greatest density?
gold
aluminum
silver
copper

Explanation:

Step1: Calcular la densidad de cada material

Dado que \(V = 1cm^{3}\), la densidad \(D=\frac{m}{V}=m\) (ya que \(V = 1\)).

• Para el oro (\(gold\)): \(m = 19,3g\), entonces \(D_{gold}=19,3g/cm^{3}\)
• Para el aluminio (\(aluminum\)): \(m = 2,7g\), entonces \(D_{aluminum}=2,7g/cm^{3}\)
• Para la plata (\(silver\)): \(m = 10,5g\), entonces \(D_{silver}=10,5g/cm^{3}\)
• Para el cobre (\(copper\)): \(m = 8,9g\), entonces \(D_{copper}=8,9g/cm^{3}\)

Step2: Comparar las densidades

\(19,3>10,5 > 8,9>2,7\)

Answer:

gold
