Respuesta :
if you look at the units of density, g/cm^3 you will see it's grams divided by volume (cm^3).
218.9 g / (0.5*1.55*25 cm^3) = 11.3 g/cm^3
218.9 g / (0.5*1.55*25 cm^3) = 11.3 g/cm^3
Answer:
Explanation:
density is defined as the measure of the mass of a matter per unit volume. it describes the sopace occupied by a substance relative to its volume.
Density = mass ÷ volume
ρ = m ÷ v
Volume = length × width × height
Volume of lead bar = l × w × h
V = 25 × 1.55 × 0.5
V = 19.375cm³
mass of bar = 218.9g
ρ = 218.9 ÷ 19.375
ρ = 11.2980g/cm³
ρ = 11g/cm³
