Question

5) A block of lead has dimensions of 4.5 cm by 5 cm by 6.0 cm. The block weighs 1502 g. From this information, calculate the density of lead.

Answer 1

Answer & Explanation:

volume of the block = 4.5 x 5 x 6 = 135 cm^3 also equal to 1.35 x 10^-4 m^3

USE THE FORMULA

Density = mass / volume

Answer in gcm^-3

Density = 1502 / 135

Density = 11.1 gcm^-3

Answer in kgm^-3

Density = 1.502 / 1.35 x 10^-4

Density = 11125.9 kgm^-3
