Question

1 using the formula ( d = m/v ), determine the identity of a cube of metal that measures 1.2 cm on each side and has a mass of 15.4 g
common metals

gold
zinc
nickel

Explanation:

Step1: Calcular el volumen del cubo

El volumen \( V \) de un cubo se calcula con la fórmula \( V = s^3 \), donde \( s \) es la longitud del lado. Dado que \( s = 1.2\,\text{cm} \), entonces \( V=(1.2)^3 = 1.728\,\text{cm}^3 \).

Step2: Calcular la densidad

Usando la fórmula \( D=\frac{M}{V} \), donde \( M = 15.4\,\text{g} \) y \( V = 1.728\,\text{cm}^3 \). Entonces \( D=\frac{15.4}{1.728}\approx8.91\,\text{g/cm}^3 \).

Answer:

Nickel
