Question

An unknown substance has a mass of 56.8 g and a volume of 23.4 ml. what is the density of this unknown substance?

Answer 1

Volume of substance = 23.4 ml = 23.4 cm3
Density = 56.8/23.4= 2.43 g/cm3 or 2.43 g/ml

Answer 2

Answer: The density of unknown substance is 2.43 g/mL

Step-by-step explanation:

Density is defined as the ratio of an object's mass and volume.

To calculate density of a substance, we use the equation:

`\text{Density of a substance}=\frac{\text{Mass of a substance}}{\text{Volume of a substance}}`

We are given:

Mass of unknown substance = 56.8 g

Volume of unknown substance = 23.4 mL

Putting values in above equation, we get:

`\text{Density of unknown substance}=(56.8g)/(23.4mL)\\\\\text{Density of unknown substance}=2.43g/mL`

Hence, the density of unknown substance is 2.43 g/mL
