Due to presence of impurities further purification is needed.
A further purification is needed of the final product because of the presence of impurities in the final product. Further purification can also be done in order to gain pure product. There are various ways and methods which can be used for the purification such as Sublimation, Crystallization, Distillation, Differential Extraction and Chromatography.
These methods can be used for further purification and helps in the extraction of pure solution of final product so we can conclude that due to presence of impurities further purification is needed.

<h3>Answer:</h3>
6278 mmHg
<h3>
Explanation:</h3>
Kilopascal (kPa) and Millimeter of Mercury (mm Hg) are both the units of Pressure. In medical science the pressure is often measured in mm of Hg.
Also,
0.133322387415 kPa equals = 1 mmHg equals
Then,
837 kpa will be equal to = X mmHg
Solving for X,
X = (837 kPa × 1 mmHg) ÷ 0.133322387415 kPa
X = 6278.0153898 mmHg
Or when rounded to 4 significant numbers,
X = 6278 mmHg
Answer:
Part 1: W = 116 Y = 163
Part 2: Since 232 is the mailing point of 2 kg then you would divide 232 by 2 to get the melting point for 1 kg, the same with Y.
The mixture can be separated as shown in the flow chart
