Prepare a 1 molar solution of NaOH 1L
Understand the Problem
The question is asking how to prepare a 1 molar (1 M) solution of sodium hydroxide (NaOH) with a total volume of 1 liter. To prepare this solution, we need to calculate the amount of NaOH required based on its molar mass and then dissolve it in water to achieve the desired concentration.
Answer
Dissolve 40 grams of NaOH in 1 liter of water.
To prepare a 1 molar solution of NaOH in 1 liter, dissolve 40 grams of NaOH in about 500 mL of distilled water, then add more water to make the total volume up to 1 liter.
Answer for screen readers
To prepare a 1 molar solution of NaOH in 1 liter, dissolve 40 grams of NaOH in about 500 mL of distilled water, then add more water to make the total volume up to 1 liter.
More Information
A 1 M solution is one that contains 1 mole of solute (in this case, NaOH) per liter of solution. The molar mass of NaOH is about 40 g/mol, so you need 40 grams of NaOH for 1 liter of 1 M solution.
Tips
A common mistake is to dissolve the NaOH pellets directly in 1 liter of water, which can result in exceeding the final volume. Always dissolve the solute in less water first and then fill it up to the final required volume.
