Answer:
1.12 g.
Explanation:
From the question given above, the following were obtained obtained:
Volume (V) of metal = 2.3 cm³
Density (D) of metal = 0.486 g/cm³
Mass (m) of metal =..?
The density of a material is simply defined as the mass of the material per unit volume of the material. Mathematically, it is expressed as:
Density (D) = mass (m) / volume (V)
D = m/V
With the above formula, we can easily calculate the mass of the metal as shown below:
Volume (V) of metal = 2.3 cm³
Density (D) of metal = 0.486 g/cm³
Mass (m) of metal =..?
D = m/V
0.486 = m/2.3
Cross multiply
m = 0.486 × 2.3
m = 1.12 g
Therefore, the mass of the metal is 1.12 g.
