Question 5: Find the mass in grams of sodium hydroxide that will be required to prepare a solution with a concentration of 0.500 mol·dm⁻³ in a 250 cm³ volumetric flask. [Round the answer to three decimal places. Do not type in the unit. Use a decimal point.] *

 

The concentration of the solution prepared in Question 5 is only approximate because sodium hydroxide is not a primary standard. *
 
 
 
A- True
B- False
Expert Solution
Step 1

From the definition of molarity (M),

Here the solute is NaOH (molar mass = 40 grams)

Molarity of the solution = mass of the solute*1000/(molar mass of the solute * volume in mL)

                   0.500 = mass of the solute *1000/(40*250) 

mass of the NaOH = 5.0 grams

mass of the solute needed to prepare 250 mL of a 0.500 M aqueous solution is 5.0 grams
