Dissolve 2 moles of NaOH in 6 kg of water?
The solution has a molar concentration of 0,33.
What is an example of a solution for science?
Try 1 molar sodium hydroxide NaOH solution and 1 molar hydrochloric acid solution HCl . Mix them together and you have a common salt solution NaCl in water. Not exactly sure what you wanted, but there you go.
What volume of 0.10 m naoh can be prepared from 250 ml of 0.30 m naoh?
10.0 ml of a solution of 6.0 molar NaOH contains (10.0/1000)(6.0) = 0.060 moles of NaOH. Call the number of milliliters needed to make a solution that is 0.30 molar with this amount of NaOH v. Then 0.060/v = 0.30, or v = 50 ml. Ideally, this solution should be made by putting the 6.0 molar solution into a volumetric container calibrated to 50 ml, then diluting with water to the mark for 50 ml. As an approximation, 50 - 10.0 = 40 ml of water can be added, but this may not give an exact match because 6.0 molar NaOH solution probably has a density considerably higher than 1.00 grams/ml, the density of water at standard temperature and pressure, while the density of 0.30 molar solution is substantially less but may still not be as low as 1.00. Therefore, adding a specified volume of water may not result in a total volume equal to the sum of the volume of water added plus the 10.0 ml originally specified.
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
How you prepare 0.01M NaOH solution?
Dissolve 40 grams of solid NaOH into enough water that it dissolves completely. Transfer this to a volumetric flask. Then add water until the volume of the solution is 1 liter. Care is needed as heat is generated which affects the volume. It is best to make up with water to about 2 cm short of the mark, allow to cool and then add the balance of the water.

What is the morality of a solution that has 120 grams of NaOH in 500 ML of solution?
6 molar

What is the molarity of a solution that contains 0.5 moles of NaOH in 200ml water?
It is 2.5 molar. The reason for this is that molarity means moles per litre. You have to multiply by 5 to get from 200ml to a litre, so you have to do the same with the moles.
What volume of 0.10 m naoh can be prepared from 250 ml of 0.30 m naoh?
10.0 ml of a solution of 6.0 molar NaOH contains (10.0/1000)(6.0) = 0.060 moles of NaOH. Call the number of milliliters needed to make a solution that is 0.30 molar with this amount of NaOH v.

What is the molarity of a solution that contains 10.0g of NaOH in 400.0 ml of NaOH of solution?
The answer is 0,625 moles.
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 molality of a solution by dissolving 2 moles of NaOH in 10kg of water?
10kg of water contains 10l of water. So morality is 0.2mildm-3.
Would the calculated molar mass be too high or too low if your standardized NaOH were exposed to the air for a long period of time after the standardization?
The molar mass remain the same but because the NaOH solution absorb carbon dioxide the titer of this standardized solution was altered.
Can we make 1N NaOH solution from 0.1N NaOH solution?
It is possible only if you evaporate the water.
