Just dissolve 8g solid NaOH in 100 mls. distilled water.
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.
Actually a 50% solution of sodium hydroxide would be made using enough water to total 100 mL of solution if using sodium hydroxide pellets or crystals. 50% of the total weight of the solution not 50% of the weight of the water used. As suggested by the first answer, the solution would be about a 33% solution. percentage solutions are weight for weight. Therefore 50% solution would be 50g of sodium hydroxide dissolved in 100g (100mL) of water.
Dissolve 30g of sodium chloride in 100 mL of water.
1.17 grams :)
what is the Ph of a solution containing 5mg/L of hydrochloric acid?
Dissolve slowly 50 g NaOH in 100 mL water; advertisement: sodium hydroxide solution is dangerous !

=20/40/100=0.0005mol/ml=0.5mol/L

To get 100g of solution: 10g of sodium thiosulfate + 90g of water.
100% Sodium Hydroxide
Dissolve 0.4 g of NaOH in 100 ml of water. Try it out. Actually it is not suitable to prepare NaOH solutions in standard flasks.It should be made in beakers & must be standardised..This is done to find the correct normality...
20 ml
Dissolve 12 g dried sodium chloride (reagent grade) in 100 mL demineralized water.
