The  volume%  of  acetone  =  Ml  of    acetone/Ml  of  solution  x100
ml   of  acetone =200ml
ml  of  solution  = 1.60  x1000=1600ml

volume%  of acetone  is  therefore=  200/1600 x100= 12.5%

velikii [3]

Answer:

/D/ either absorbs or releases energy

Explanation:

During a phase change energy is either absorbed or released.

A phase change is a reversible process which occurs when a substance changes is its state from one form to another.

Phase changes are used to delineate physical changes.

  • A phase diagram provides a graphic representation of the change.
  • The diagram can be 2 dimensional or 3 dimensional.

what concept from chemistry was the most challenging and why? what can you do to learn more about this concept as you progress t
qwelly [4]

The most difficult concept will be the concept of patient drug tolerance because there are many drugs that have different side effects for different patients. Therefore, it is necessary to understand the response of certain drugs to different patients. This will help avoid wrong drug combinations. This can cause side effects.

To learn more about this concept, you need to do your homework on these different drugs and the tolerance reactions you may experience, and attend some drug tolerance seminars, where the speaker will give you more ideas . And a further explanation of the concept.

Another topic in chemistry that is most tough to understand is moles. We can understand this concept by understanding the fact mole is an amount of a substance which may be atoms, molecules, ions, etc which have exactly 6.02214076 * 1023 'elementary entities' of the substance.
