You need to know the gram molecular mass (in this instance, since sodium chloride is an ionically bonded compound and does not have moles in the strictest sense, more properly the gram formula unit mass) of sodium chloride, which is 58.44. The number of grams required may be calculated as set forth below.
By definition, a 0.05M solution contains 0.05 moles of solute (sodium chloride in this instance) per liter of solution, and there are 1000 ml per liter. Therefore, the number of moles required for the specified amount of 0.05M solution is 0.05(125/1000) or 0.00625. The amount of sodium chloride required is therefore 0.00625(58.44) or 0.4 grams, to the justified number of significant digits, which is limited by the fact that the molar concentration stated has only one significant digit. If 0.05 were interpreted as having at least three significant digits, then the answer would be 0.3652 grams.

What is a concentration of a solution?
The concentration of a solution is basically how strong the solution is.
How do you prepare saturated solution given 1gram of oxalic acid in 7g of water?
1 gram Oxalic Acid in 7 ml of water at room temperature - 1 gram per 2 ml of hot water will provide saturated solution.
Is concentration typically given with the volume of solvent or the volume of solution?
The concentration of a solution is typically given in terms of the volume of solution, in liters.
What is the amount of solute that dissolves in a given amount of a solution?
This term is concentration, expressed in g/l, mol/L, mg/L, etc.
There are several ways to express solution concentration dilute concentrated ppm molarity molality normality All of these have one thing in common They describe the what?
quantity of solute dissolved in a given quantity of solvent
How do you make a 10 percent aqueous solution of potassium hydroxide?
Weigh 10g of the given sample and dissolve it in 100ml of water, it forms a 10% solution of that sample.
Who would you prepare 2.6L of a 1200 solution given 12 percent solution sterile water?

How do you prepare 50 percent potassium fluoride solution?
Assuming the given solution is 50% w/w, we add equal amounts of water and KF so as to get the solution in desired quantity.
What is the molarity of Na Cl in a graduated cylinder with 100ml of distilled water?
There isn't enough to answer your question. You've given a volume, but haven't given a weight or amount of moles. I also do not know if there is a relevance to your including the graduated cylinder. A solution should always be made up in a volumetric flask.
Will potassium cause tissue necrosis if given IV Push?
If given in a concentration over 40mEq/l per peripheral line, or over 20mEq/100ml by central line, KCl can be sufficiently injurious as to cause phlebitis or even necrosis, especially if the solution infiltrates outside the vessel.

a pOH of 10.7 was recorded. What will be the pH value of that given solution?
During the neutralization of a given solution in the lab, a pOH of 10.7 was recorded. What will be the pH value of that given solution?
Could you prepare oxalic acid by adding HCl to a solution of sodium oxalate cooling it to room temp and filtering the resulting mixture?
No we cannot prepare Oxalic acid by the given method. Solubility of Sodium Oxalate is less in comparison to solubility of Oxalic acid. So whatever oxalic acid is formed will remain in the solution and cannot be precipitated out in the form of solid
