How many grams of solute are required to make a 918 mL solution of sodium hydroxide with a concentration of 0.4922 M?
Dfhgtrwryrtgsdffgqe6...
Molarity = moles of solute/Liters of solution ( 918 ml = 0.918 liters )
rearranged algebraically,
moles of solute = Liters of solution * Molarity
moles of NaOH = (0.918 l)(0.4922 M)
= 0.45184 moles NaOH
=======================so,
0.45184 moles NaOH (39.998 grams/1 mole NaOH)
= 18.1 grams sodium hydroxide needed

What is the purpose of titrating sodium hydroxide with an acid solution?
Determination of the concentration of sodium hydroxide in solution with the help of a neutralization reaction.
Would it matter if droplets of distilled water were left in the buret when it was filled with sodium hydroxide?
Yes, as it will serve to dilute the concentration of the sodium hydroxide being placed in the buret. You will being adding a known concentration of sodium hydroxide and ending up with an unknown concentration.
Does sodium hydroxide have pH 7?
No, sodium hydroxide (NaOH) does not have a pH of 7. Sodium hydroxide is a strong base and has a pH greater than 7. The pH of a solution of sodium hydroxide depends on its concentration. A 0.1 M solution of NaOH has a pH of 13.
How do you calculate of NaOH in solution procedure?
The concentration of sodium hydroxide in solution is determined by titration with an acid solution.
What percentage solution equals a 1 normal solution of sodium hydroxide?
Sodium hydroxide 1 N (normal solution) solution has a concentration of39,99710928 g/L (rounded 40 g/L) or 4 g/100 mL sodium hydroxide in water.
Is sodium hydroxide unknown solution?
Sodium hydroxide is not an unknown solution.
How can you calculate the concentration of a phosphoric acid solution from the titration with sodium hydroxide?
With a calculator. That is the easiest way.
What is the pH number of sodium hydroxide?
Sodium hydroxide does not have a pH number. The pH of a solution of sodium hydroxide depends entirely on the concentration of it in that solution. To learn how to determine the pH of a sodium hydroxide solution, see the Related Questions links.
Is sodium hydroxide solution neutral?
No. A sodium hydroxide solution is very basic.
What is the concentration of a solution with a volume of 0.50 L that contains 40.0 grams of sodium hydroxide?
2.0 M
Determination the concentration of concentrated hydrochloric acid?
Method: titration with a standardized solution of sodium (or potassium) hydroxide.
How do you determine the concentration of concentrated hydrochloric acid?
