Question

magnesium is a fairly light metal that is combined with other elements to form lightweight alloys for use in airplanes. the big advantage of magnesium is that it has a relatively low density of 1.74 grams/cm³. if a sample of magnesium has a mass of 9.56 grams, what is its volume?

Explanation:

Step1: Identificar la fórmula

La densidad $
ho$ está dada por $
ho=\frac{m}{V}$, donde $m$ es la masa y $V$ es el volumen. Despejamos $V$: $V = \frac{m}{
ho}$.

Step2: Sustituir valores

Tenemos $m = 9.56$ gramos y $
ho=1.74$ gramos/cm³. Sustituyendo en la fórmula $V=\frac{9.56}{1.74}$.

Step3: Calcular el volumen

$V=\frac{9.56}{1.74}\approx5.5$ cm³.

Answer:

$5.5$ cm³
