300g NaOH + 700g water
Dissolve slowly 50 g NaOH in 100 mL water; advertisement: sodium hydroxide solution is dangerous !
to prepare 1N we have to dilute 40gms of NaOH in 1 litre of water as for NaOH normality =molarity so to prepare 0.1N NaOH we have to dilute 4gms of NaOH in 1 litre of water..
0,4 g NaOH + 1000 ml H2O
no-AH
"Dilute NaOH" without any other specifications in a chemistry lab generally refers to a 6M solution of NaOH in water.

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...
0,4 g NaOH + 1000 ml H2O

30 ml of ethanol to 70ml of distilled water.
30% Acrylamide 100g Acrylamide 2.6g Bis H2O to 330ml

You need 2,4 g NaOH (0,06 moles).
40 grams, this is the 1M NaOH standard laboratory solution.
Concentration of NaOH = 0.025 M = 0.025 Moles per Litre of SolutionVolume of Solution required = 5.00LWe can say therefore that:Number of Moles of NaOH needed to prepare the solution= Concentration of NaOH * Volume of Solution requiredTherefore:Number of Moles of NaOH needed to prepare the solution= 0.025M * 5.00L= 0.125molesFrom this we can say that 0.125 moles of NaOH are needed to prepare a 5.00 L solution with a concentration of 0.025M of NaOH.
Dissolve 30 g KOH in 100 mL methanol.
