Question

A flask with a mass of 321.9 g is filled with 15.7 mL of carbon tetrachloride. The mass of the flask and carbon tetrachloride is found to be 523.6 g. From this information, calculate the density of carbon tetrachloride. According to this problem, the density of CCl4 is Answer g/mL.

Answer 1

Density of carbon tetrachloride = 12.8 g/mL

Step-by-step explanation:

Given :

`m_(flask)=321.9\ g`

`m_(flask)+m_(CCl_4)=523.6\ g`

Mass of carbon tetrachloride: -

`m_(flask)+m_(CCl_4)=523.6\ g`

`m_(CCl_4)=523.6-m_(flask)\ g=523.6-321.9\ g=201.7\ g`

Mass of carbon tetrachloride = 201.7 g

Given, Volume = 15.7 mL

Considering the expression for density as:

`Density=\frac {Mass}{Volume}`

So,

`Density=\frac {201.7\ g}{15.7\ mL}`

Density of carbon tetrachloride = 12.8 g/mL
