Volume of Acetone = 28.56ml
Mass in grams = ?
For the density of Acetone which has Propanone in IUPAC names,
we will find that density is 0.7925g/cm3. This is the same as 0.7925g/ml.
Now by using the formula
Density = Mass / Volume
Mass = Density x Volume
Putting the values of density and volume in formula,
Mass = 0.7925g/ml x 28.56ml
<span>Mass = 22.63g </span>
<span>so the mass is 22.63g </span>
Answer:
from the spaces left between chains when the polymer is
formed.
Explanation:
Polyethylene polymer may be of high or low density. Whether the polymer is of high or low density depends on the arrangement of the polymer chains.
If the polymer chains are close together such that the resultant polymer is crystalline with chains packed closely, we have high density polyethylene.
On the other hand if the chains are not close together and there are spaces left between chains when the polymer is formed, then we have low density polyethylene.
Hence, low density polyethylene gets its name from the spaces left between chains when the polymer is formed.
