What is the concentration of a solution with a volume of 0.50 L that contains 40.0 grams of sodium hydroxide?
To find the concentration, we need to calculate the molarity (M) of the solution. First, calculate the molar mass of sodium hydroxide (NaOH) which is 40.00 g/mol. Next, divide the mass of NaOH by its molar mass to get moles. Finally, divide moles by the volume in liters (0.50 L) to find the concentration in moles per liter.
What is the pH of 10 mol per liter of sodium hydroxide solution?
The pH of a 10 M sodium hydroxide solution would be around 14, as sodium hydroxide is a strong base that dissociates completely in water to yield hydroxide ions, which are responsible for the high pH.
What percentage solution equals a 1 normal solution of sodium hydroxide?
A 1 normal solution of sodium hydroxide is equivalent to a 4% solution. This is because normality is a measure of the number of equivalents (gram equivalent weight) of a substance per liter of solution, while percentage is a measure of the mass of solute per 100 parts of solution.
What is the ionic formula for sodium hydroxide?
NaOH and H2O form a solution of Na+(aq) and OH-(aq) ions (the solvent water, aq, is written as subscripted (aq) ) To make 1 Normal solution you need to know the equivalent of NaOH, which is calculated by dividing Molecular weight by 1, that is 40 divided by 1= 40. So the equivalent weight of NaOH is 40. To make 1 N solution, dissolve 40.00 g of sodium hydroxide in water to make volume of 1 liter.
What is the make up of 0.1 sodium hydroxide?
0.1 M sodium hydroxide solution contains 0.1 moles of sodium hydroxide per liter of solution. This corresponds to 0.1 moles of NaOH per 40 g (1 mole) of NaOH, resulting in 4 g of NaOH in 1 liter of 0.1 M NaOH solution.
What is the molarity of a 3 sodium hydroxide solution?
A 3 M sodium hydroxide solution means there are 3 moles of sodium hydroxide dissolved in 1 liter of solution.
An aqueous solution of sodium hydroxide contained in a bottle is labelled 2M. Determine the mass of sodium hydroxide used in preparing?
To determine the mass of sodium hydroxide used in preparing a 2M solution, you need to know the volume of the solution you are preparing. The concentration of 2M means there are 2 moles of sodium hydroxide in 1 liter of solution. You can use the formula: mass = molarity x volume x molar mass to calculate the mass of sodium hydroxide. For example, if you are preparing 1 liter of the solution, the mass would be 2 x 1 x 40 g/mol (molar mass of NaOH) = 80 grams.

0.1 M sodium hydroxide solution contains 0.1 moles of sodium hydroxide per liter of solution. This corresponds to 0.1 moles of NaOH per 40 g (1 mole) of NaOH, resulting in 4 g of NaOH in 1 liter of 0.1 M NaOH solution.
How many gm of NaOH are required to make one liter of a solution?
As many as you like, depending on what you want the concentration to be. (Solubility will eventually become a factor, but sodium hydroxide is pretty darn soluble.)
What is molar quantity?
Molecular weight (unit) of salt dissolved in liter (unit) volume of water.
What does M mean in the following - 0.01 M sodium dodecyl sulphate and 2 ml of acetic acid per liter?
M means molar. Molar is how many moles per litre. The moles can be calculated by dividing the mass in grams by the molecular weight as seen in the periodic table
How much water should be added to 98 mg of sodium azide to give a 1 molar solution?
To make a 1 molar solution of sodium azide, you would need to dissolve 65.01 g of sodium azide in water to make 1 liter of solution. Since you have 98 mg of sodium azide, you would need to add enough water to make a final volume of 1 liter to create the 1 molar solution.
How do you make molar solutions?
To make a molar solution, you need to dissolve the molecular weight of a substance in one liter of solvent. This is done by measuring the amount of substance needed based on its molar mass and then adding it to the solvent until it reaches a final volume of one liter.
