Question

A piece of lead weighs 348g . If its volume is 30 cubic cm, what is the density of Lead​

Answer 1

Answer:

Given :-

• A piece of lead weight 348 g.
• The volume is 30 cm³.

To Find :-

• What is the density of lead.

Formula Used :-

$\clubsuit$ Density Formula :

$\mapsto \sf\boxed{\bold{\pink{\rho =\: \dfrac{m}{v}}}}$

where,

• $\sf \rho$ = Density
• m = Mass
• v = Volume

Solution :-

Given :

• Mass = 348 g
• Volume = 30 cm³

According to the question by using the formula we get,

$\longrightarrow \bf \rho =\: \dfrac{m}{v}$

$\bigstar\: \: \sf\bold{\purple{Density =\: \dfrac{Mass}{Volume}}}\: \: \bigstar$

$\longrightarrow \sf Density =\: \dfrac{348}{30}$

$\longrightarrow \sf\bold{\red{Density =\: 11.6\: g/cm^3}}$

${\small{\bold{\underline{\therefore\: The\: density\: of\: lead\: is\: 11.6\: g/cm^3\: .}}}}$

Answer 2

Answer:

• 11600 Kg/m³.

Explanation:

We have,

• Mass (m) = 348 g
• Volume (v) = 30 cm³

To find,

• Density (ρ)

Solution,

> ρ = m/v

=> ρ = 348/30

∴ ρ = 11.6 g/cm³

_______________

> ρ = 11.6 g/cm³

=> ρ = 11.6 × 1000 Kg/m³

∴ ρ = 11600 Kg/m³

• Hence, the density of lead is 11600 Kg/m³.
