Answer:

Endocrine disruptor

Explanation:

This means that the four substances, even they are used in different areas like gardening, plastics or pots, all of them change the endocrine system in humans because they imitate the natural hormones and the body stops to produce them or starts to produce more hormones than the body needs.

They are correlate with some illness like cancer, thyroid problems and infertility.

Suppose you have a sample of table salt (NaCl) that has a mass of 100.0 grams. If
IgorC [24]

Taking into account the definition of molarity, the concentration of the solution is 0.855 \frac{moles}{liter}.

<h3>Definition of molarity</h3>

Molar concentration or molarity is a measure of the concentration of a solute in a solution and indicates the number of moles of solute that are dissolved in a given volume.

The molarity of a solution is calculated by dividing the moles of solute by the volume of the solution:

Molarity=\frac{number of moles}{volume}

Molarity is expressed in units \frac{moles}{liter}.

<h3>Molarity of NaCl</h3>

In this case, you have:

  • number of moles of NaCl= 100 grams\frac{1 mole}{58.45 grams} =1.71 moles (being 58.45 g/mole the molar mass of NaCl)
  • volume 2 L

Replacing in the definition of molarity:

Molarity=\frac{1.71 moles}{2 L}

Solving:

Molarity= 0.855 \frac{moles}{liter}

Finally, the concentration of the solution is 0.855 \frac{moles}{liter}.
