Answer : The density of a sample is, 34.2 g/L
Explanation :
Density : It is defined as the mass contained per unit volume.
Formula used for density :
Given :
Mass of a sample = 7.412 grams
Volume =0.217 L
Now put all the given values in the above formula, we get the density of a sample.
Therefore, the density of a sample is, 34.2 g/L
Answer:
Chloroform is expected to boil at 333 K (60 ).
Explanation:
For liquid-vapor equilibrium at 1 atm, = 0.
We know, , where T is temperature in kelvin scale.
Here both and
are corresponding to vaporization process therefore T represents boiling point of chloroform.
So,
or, T = 333 K
So, at 333 K (60 ) , chloroform is expected to boil.
