Answer:
11267.61 Kg/m³.
Explanation:
From the question given above, the following data were obtained:
Mass of lead = 32 g
Volume of lead = 2.84 cm³
Density of lead =.?
Next, we shall convert 32 g to Kg. This can be obtained as follow:
1000 g = 1 Kg
Therefore,
32 g = 32 g × 1 Kg / 1000 g
32 g = 0.032 Kg
Next, we shall convert 2.84 cm³ to m³. This can be obtained as follow:
1 cm³ = 10¯⁶ m³
Therefore,
2.84 cm³ = 2.84 cm³ × 10¯⁶ m³ / 1 cm³
2.84 cm³ = 2.84×10¯⁶ m³
Finally, we shall determine the density of the piece of lead. This can be obtained as follow:
Mass of lead = 0.032 Kg
Volume of lead = 2.84×10¯⁶ m³
Density of lead =.?
Density = mass / volume
Density of lead = 0.032 / 2.84×10¯⁶
Density of lead = 11267.61 Kg/m³
