Question

You have a sample of lead with a volume of 12 cm3. Lead has a density of 11.3 g/cm3. What is the mass of the lead?

Answer 1

Answer:

132.36 g

Explanation:

Since Density = Mass / volume

Answer 2

Given:

• Volume of lead = 12 cm³
• Density of lead = 11.3 g/cm³

To find:

Mass of lead ?

Calculation:

• Mass can be calculated as the product of density and volume.

• SI unit of mass is kg , but here we will calculate in grams.

$\therefore \: mass = volume \times density$

$\implies \: mass = 11.3 \times 12$

$\implies \: mass = 135.6 \: grams$

$\implies \: mass = \dfrac{135.6}{1000} \: kg$

$\implies \: mass \approx 0.136 \: kg$

So, mass of lead in that sample is 0.136 kg.
