A chemist prepares a solution of sodium chloride by measuring out of sodium chloride into a volumetric flask and filling the flask to the mark with water. Calculate the concentration in of the chemist's sodium chloride solution. Be sure your answer has the correct number of significant digits.

4.35 mol/L

Explanation:

There is some info missing. I think this is the original question.

A chemist prepares a solution of sodium chloride by measuring out 25.4 grams of sodium chloride into a 100 mL volumetric flask and filling the flask to the mark with water. Calculate the concentration in mol/L of the chemist's sodium chloride solution. Be sure your answer has the correct number of significant digits.

Step 1: Calculate the moles of sodium chloride

The molar mass of sodium chloride is 58.44 g/mol. The moles corresponding to 25.4 grams of sodium chloride are:

Step 2: Calculate the liters of solution

We will use the relationship 1 L = 1,000 mL.

Step 3: Calculate the concentration of sodium chloride in mol/L

periodic trends is an atom that gets larger as the number of electronic shells increase, the radius of atoms increases as you go down a certain group in the periodic table of elements. in general, the size of an atom will decrease as you move from left to right of a certain period.
