4 0

<span>The systemic study of natural world is called natural science. It is concerned with the understanding of natural phenomena based on collected data, knowledge or sense of experience by means of observation and experimentation. Natural science is subdivided into two main branches: one is biological science or life science which aims to study life and living organisms their function, structure, evolution, growth, distribution and taxonomy second is physical science which is also broken down into different branches, including Earth science, astronomy, chemistry and physics. </span>

There are 258 g of MgCl2/liter. What is the molarity of the solution?

Zolol [24]

Taking into account the definition of molarity, the molarity of the solution is 2.7098 moles of MgCl₂/liter.

<h3>Definition of molarity</h3>

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= number of moles÷ volume

<h3>Molarity of the solution in this case</h3>

In this case, you know that the molar mass of MgCl₂ is 95.21 g/mole [molar mass is the amount of mass that a substance contains in one mole.]

You can apply the following rule of three: If by definition of molar mass 95.21 grams are contained in 1 mole, 258 grams are contained in how many moles?

amount of moles= (258 grams× 1 mole)÷ 95.21 grams

<u><em>amount of moles= 2.7098 moles</em></u>

Replacing in the definition of molarity:

258 g of MgCl₂/liter= <u><em>2.7098 moles of MgCl₂/liter</em></u>

<em />

Finally, the molarity of the solution is 2.7098 moles of MgCl₂/liter.
