Question

Calculate the density of chloroform

Answer 1

The density of chloroform at 20°C is 1.4832 g/mL.

Density is a measure of mass per unit volume. It is typically expressed in units such as kilograms per cubic meter (kg/m³) or grams per cubic centimeter (g/cm³). The formula for density is:

`Density=MassVolumeDensity= VolumeMass`

​The density of chloroform can be calculated using the following equation:

Density = (mass of chloroform) / (volume of chloroform)

From the image, we can see that the mass of the chloroform is 145.10 g and the volume of the chloroform is 40.5 mL. Therefore, the density of chloroform is:

Density = (145.10 g) / (40.5 mL) = 3.58 g/mL

However, the image also states that the temperature is 20°C. At this temperature, the density of chloroform is known to be 1.4832 g/mL. Therefore, the answer to the question is:

The density of chloroform at 20°C is 1.4832 g/mL.

Answer 2

Answer: The density of chloroform is 1.47 g/mL

Explanation : Given,

Volume = 40.5 mL

Mass of cylinder = 85.16 g

Mass of cylinder and liquid = 145.10 g

First we have to calculate the mass of liquid (chloroform).

Mass of liquid = Mass of cylinder and liquid - Mass of cylinder

Mass of liquid = 145.10 g - 85.6 g

Mass of liquid = 59.5 g

Now we have to calculate the density of liquid (chloroform).

Formula used:

`Density=(Mass)/(Volume)`

Now putting g all the given values in this formula, we get:

`Density=(59.5g)/(40.5mL)`

`Density=1.47g/mL`

Therefore, the density of chloroform is 1.47 g/mL
