Question

The density of silver is 10.3g/cm³.Find the mass of silver block of volume 200cm³​

Answer 1

Answer:

Pls mark me as brainliest

Explanation:

Density = Mass / Volume

Density = 10.3 g/cm³

Volume = 200 cm³

Mass = 10.3 × 200 = 2060 g = 2060/1000 kg = 0.206 kg

Answer 2

Answer :

➥ The mass of a silver block = 0.2060 kg

Given :

➤ Density of a silver block = 10.3 g/cm³

➤ Volume of a silver block = 200 cm³

To Find :

➤ Mass of a silver block = ?

Required Solution :

For solving this question, let's first know about Mass

A Mass is used to measure the weight of an object.

• The SI unit of a mass is kilograms.
• Mass is abbreviated by kg.
• Mass is a scalar quantity.

Let's solve this question...

We can find Mass of a silver block by using the formula of mass which says m = ρ × v.

Here,

• m is the mass in kg.
• ρ is the density in g/cm³.
• v is the density in cm³.

✎ So let's find the mass of a silver block (m) !

→ m = ρ × v

→ m = 10.3 × 200

→ m = 2060 g

Converting g into kg :

→ m = 2060 g

→ m = 2060/1000

→ m = 0.2060 kg

Formulae of mass :

⪼ m = w/g

Where,

• w is the weight.
• m is the mass.
• g is the gravity.

⪼ m = ρ × v

Where,

• m is the mass.
• ρ is the density.
• v is the volume.

⪼ m = F/g

Where,

• F is the force.
• G is the gravity.

⪼ m = (E/c²)

Where,

• m is the mass.
• E is the energy.
• c is the speed of light (3×10⁸ m/s).
