Answer:

First off, well-being is defined as the overall evaluation a person makes regarding their life and emotional experiences. It's the combination of "feeling good" or positive affect, low levels of negative affect or negative feelings, and life satisfaction (a broad cognitive appraisal regarding one's life). A part of well-being is determined by the direct attempt that people make to influence their own well-being (their internal actions). 3 ways out of many that people can do this is through optimism, positive emotions, and forgiveness.

How many grams of sodium chloride must be added to make 400. ml of a 0. 600 m sodium chloride

raketka [301]

Taking into account the definition of molarity, 14.028 grams of sodium chloride must be added to make 400 mL of a 0.600 M sodium chloride.

<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>Moles of sodium chloride</h3>

In this case, you know:

Molarity= 0.600 M
number of moles= ?
volume= 400 mL= 0.400 L (being 1000 mL= 1 L)

Replacing in the definition of molarity:

$0.600 M=\frac{number of moles}{0.400 L}$

Solving:

number of moles= 0.600 M× 0.400 L

number of moles= 0.24 moles

<h3>Mass of sodium chloride</h3>

Being the molar mass of sodium chloride 58.45 $\frac{g}{mole}$ , that is the amount of mass that a substance contains in one mole, the mass of sodium chloride can be calculated as:
