When a person pushes off a wall with 15N of force,how much force does the wall push back
aivan3 [116]
Newton's third law of motion states that for every action force, there is an equal and opposite reaction force so that means that the wall is pushing you with the same amount of force that you put on it.

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}.
