Question

The density of lead is 11.3 g/cm 3. What mass of lead is required to make a 1 cm 3 fishing sinker?

Answer 1

Answer:

11.3 g

Explanation:

Parameters given:

Density of lead, D = $11.3 g/cm^3$

Volume of fishing sinker, V = $1 cm^3$

Density is a characteristic of a substance and it is the measure of the mass per unit volume. Mathematically:

$Density = \frac{mass}{volume} \\\\\\D = \frac{m}{v}$

That means that mass is:

$Mass = Density * volume$

Therefore, the mass of lead needed to make the fishing sinker:

$Mass = 11.3 * 1\\\\\\Mass = 11.3 g$

Answer 2

Answer:

11.3 g

Explanation:

given,

density of the lead = 11.3 g/cm³

volume = 1 cm³

mass of the lead = ?

we know,

$density=\dfrac{mass}{volume}$

mass = volume x density

mass = 1 x 11.3

mass = 11.3 g

hence, the mass of the lead is equal to 11.3 g
