Final Answer:
80 mm³ of lead would weigh 0.912 grams.
Step-by-step explanation:
Given that the density of lead is 11.4 g/cm³, to find the weight of 80 mm³ of lead, the density formula (Density = Mass / Volume) can be rearranged to find the mass (Mass = Density × Volume).
First, convert 80 mm³ to cm³. Since 1 cm³ = 1 mL, the conversion is straightforward: 80 mm³ is equivalent to 0.08 cm³ (80 mm³ ÷ 1000 = 0.08 cm³).
Now, use the formula Mass = Density × Volume. Multiply the density of lead (11.4 g/cm³) by the volume in cm³ (0.08 cm³) to find the mass. Mass = 11.4 g/cm³ × 0.08 cm³ = 0.912 grams.
Understanding density as a measure of mass per unit volume helps in calculating the mass or weight of a substance given its volume and density. Converting units appropriately, such as from mm³ to cm³, ensures consistency in calculations involving volume.
Knowing the relationship between density, mass, and volume enables precise measurements and calculations in various scientific fields, including chemistry, physics, and material sciences.
