Question

calculate the density of a substance whose mass is 5.4g and volume is 2cm³

please answer in full procedure ​

Answer 1

━━━━━━━━━━━━━━━━━━━━

✤ Required Answer:

✒ GiveN:

• Mass of the substance = 5.4 g
• Volume of the substance = 2 cm³

✒ To FinD:

• Density of the substance.....?

━━━━━━━━━━━━━━━━━━━━

✤ How to solve?

First of all, We should know what density of a substance means? And, how it is related to mass and volume...!

• Density (ρ) of a substance is mass per unit volume. It means, density remains constant for a certain substance inregardless of its size and shape.

It can be written as,

$\large{ \cdot{ \boxed{ \sf{ \rho = \frac{m}{v} }}}}$

Where, ρ is the density, m is the mass and v is the volume of the certain substance. So, by using this, let's solve the question.

━━━━━━━━━━━━━━━━━━━━

✤ Solution:

We have,

• m = 5.4 g
• V = 2 cm³

By using formula,

➝ ρ = m/V

➝ ρ = 5.4 g/ 2 cm³

➝ ρ = 2.7 g/cm³

✒ Therefore, Density of the substance = 2.7 g/cm³.

Unit conversion g/cm³ ➝ kg/m³,

➝ 1 g/cm³ = 1000 kg/m³

➝ 2.7 g/cm³ = 2.7 × 1000 kg/m³

➝ 2.7 g/cm³ = 2700 kg/m³

✒ In terms of kg/m³, the density of the substance = 2700 kg/cm³.

Answer 2

Answer:-

Given that,

Mass [m] = 5.4g

Volume (V) = 2cm^3

Denisty (P) = ?

We know that,

P = m/V

P = 5.4/2

=> 2.7g/cm^3
