Taking into account the definition of molarity, the concentration of CH₃OH in the solution is 3.12 \frac{moles}{liters}.

<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}{liters}.

<h3>Concentration of CH₃OH</h3>

In this case, you know:

  • number of moles= 50 g× \frac{1 mole}{32.04 g}= 1.56 moles, being 32.04 \frac{g}{mole} the molar mass of CH₃OH
  • volume= 500 mL= 0.5 L (being 1000 mL= 1 L)

Replacing in the definition of molarity:

Molarity=\frac{1.56 moles}{0.500 L}

Solving:

<u><em>Molarity= 3.12 </em></u>\frac{moles}{liters}

Finally, the concentration of CH₃OH in the solution is 3.12 \frac{moles}{liters}.

What is the most likely effect of deforestation that results from urbanization of an area?
dsp73
The effect of deforestation due to urbanization is partly to lose habitat for wildlife that lived in the forest and also it can increase erosion if it is on a mountainside with somewhat steep terrain, for example. On the other hand, once a new section of city is developed properly, it may have have new parks which can provide some habitat for small animals like squirrels and also birds.
