What is the meaning of 50 percent NaOH aqueous solution?
100 g of solution containing 50 g of NaOH.
What is the molarity of a solution made by dissolving 3.09 moles of Nacl in 1.50 L of solution?
what is the molarity of a solution prepared by dissolving 36.0g of NaOH in enough water to make 1.50 liter of solution?
How can you Prepare 5 N NaOH?
It's very easy as the molarity and normality of NaOH is the same. so all you need to do is to decide how much (volume) of that you need. the molar mass of NaOH is 40.5 gr, so 5 molar (normal) solution needs times five of that in 1 litre. 5*40.5=202.5 dissolve it in 1 liter water (be careful as the dissolving process is highly exothermic) Now you have 1 litre of 5 normality NaOH.
How do you prepare a 50 percent of NaOH solution?
Dissolve slowly 50 g NaOH in 100 mL water; advertisement: sodium hydroxide solution is dangerous !
What is the molarity of NaOH in a 100ml of water when 400mg of NaOH is added?
40 g NaOH in 1 liter is 1 molar. So 400 mg = 0.4 g in 100 ml = 4 g per liter and thus 0.1 molar.
What is the meaning of 50 percent NaOH aqueous solution?
100 g of solution containing 50 g of NaOH.
What is the pH of the solution formed when 100 milliliter of hcl is mixed with 100 milliliter of NaOH?
I think it'd be pH 7. Same amount of both, providing they are the same molarity!
What is the molarity of a solution that contains 0.73 moles of NaOH in 353 mL of water?
Molarity is moles per litre. So here, you have to divide by 353ml, x 1000 (to get it per litre). .73/353*100 is 2.07 molar.
What is the molarity of a solution made by dissolving 3.09 moles of Nacl in 1.50 L of solution?

The molarity of a solution of 5.0 g of KCl in 100 mL of solution is?
0.67 M

40 g NaOH in 1 liter is 1 molar. So 400 mg = 0.4 g in 100 ml = 4 g per liter and thus 0.1 molar.
5.012g of oxalic acid hydrate is dissolved in enough water to make 100 ml of solution. this solution is stitrated with a standardized NaOH solution. It required 39.40 ml of 2.02 M NaOH to reach the?
endpoint
How much 2.5 M NaOH is necessary to create 500 ml of 0.100 M NaOH?
A 0.205 M solution will have 0.205 moles per liter. 250 milliliters is 1/4 of a liter, so in that sample, there will be 0.05125 moles. NaOH has a molar mass of 39.9971 grams per mole, so 2.05 grams added to 250 mL of water will make the desired solution.
What will be the molarity for a solution prepared by dissolving a 10 grams compound with a molecular mass of 100 in 1 L of water?
Molarity = moles of solute/Liters of solution 10 grams of compound ( 1mol/100g ) = 0.1 mole Molarity = 0.1 mol/1 Liter = 0.1
How do you prepare 0.5 N NaOH solution?
There is 0.5 moles of NaOH per litre To calculate 0.5 molar NaOH first know the molecular weight of NaOH i.e 40 now multiply the number of moles of NaOH you have (0.5) found as above. so to find the number of grams of NaOH we needed to start with (0.5) * (40) = 20g So dissolve 20g of NaOH in one litre of the solution to prepare 0.5 molar solution
