Mass of solute that is KCl given as=14.0 g

Mass of the solution=Volume \times density

Mass of the solution=78 mL\times 1g cm^{-3}

Mass of the solution=78 g

weight/weight % of the solute=\frac{Mass of the solute}{Mass of the solution}\times 100

weight/weight % of the solute that is KCl=\frac{14}{78}\times 100

weight/weight % of the solute that is KCl=17.9

So the weight/weight % of the solute that is KCl found to be 17.9 .

When scientists create a representation of a complex process, they are
Burka [1]

Answer:

d making models.

Explanation:

When scientists create a representation of a complex process, they are inferring that they are making models.

A model is an abstraction of the real world or a complex process. Models are very useful in developing solutions to processes that are not easily simplified.

  • The models allow a part of a body to be simply studied.
  • Through this simple abstraction, extrapolations to other parts of the system can be deduced.
  • This can give very useful insights into the other parts of the system.
  • The heterogeneity of complex processes is a huge limitation to understanding them.
  • A homogenous part can be modelled and used to understand the system.
