What happens to the molarity of a salt solution if the number of moles of salt in the solution is multiplied by three and the nu

Dovator [93]

Answer:

The molarity of the solution remains unchanged.

Explanation:

Consider the formula for the molarity $M$ of a solution:

$\displaystyle M = \frac{n}{V}$ ,

where

$n$ is the number of moles of solute in this solution, and
$V$ is the volume of the solution.

For this salt solution,

$n_{1} = 3\;n_{0}$ , and
$V_{1} = 3\;V_{0}$ .

Initial molarity:

$\displaystyle M_{0} = \frac{n_{0}}{V_{0}}$ .

Final molarity:

$\displaystyle M_{1} = \frac{n_{1}}{V_{1}} = \frac{3\;n_{0}}{3\;V_{0}} = \frac{n_{0}}{V_{0}} = M_{0}$ .

In other words, the molarity of the solution remains unchanged.

Metals experience plastic deformation when _____.

xxTIMURxx [149]

Metals experience plastic deformation when a specific amount of pressure and temperature is applied to them. Most metals have low specific heat. Because of their low specific heat, they easily get hot when heat is applied to them.

Could you have identified a physical property of a substance before you performed the activity? Explain.

sasho [114]

You could identify a physical property of a substance before you performed the activity because the characteristics of a material known as its physical qualities are those that may be investigated independently of the substance's chemical makeup.

This is further explained below.

<h3>What is physical property?</h3>

Generally, Any attribute that can be measured and has a value that can be used to describe the state of a physical system is considered to be a physical property.

In conclusion, The changes that take place in a system's physical attributes may be utilized to provide a description of the transitions that take place between its momentary states.
