Percent concentration could mean many things...
MOLARITY is defined as the moles of solute per unit volume of solution so 5 moles of NaCl in one liter of solution would be 5M (molar) NaCl solution.
(Note: Solution is the solvent and solute combined, usually the solid is added and then the solution is filled to a certain line once the solid has dissolved.)
MOLALITY is defined as the moles of solute per kilogram of solvent (NOT solution). So 5 moles of NaCl in one kilogram of water makes 5 mol/kg NaCl. (sometimes the symbol m is used for molality but is often confused with the unit of meters).
For other types of "percent concentration" of solutions check:

A cursory glance seemed to confirm the accuracy of the information.

A solution contains 1.20 g of CaCl2 and 240 mL of solution what is the percent w-v concentration of the solution?
W-V percent concentration g/mL = 1.20g/240mL = 0.005 g/mL percent
What if a semipermeable membrane has a 2 percent salt solution on one side a 15 percent salt solutionWhat will mostly occur?
Osmosis of water from a low concentration of salt to a high concentration
What kind of water has a salt concentration of about 3.5 percent?
salt water
How do you convert 5.9 milligram per gram into percent concentration?
1 milligram = 1/1000 gram 5.9 milligram/gm = 5.9/1000 grams/gm the percent concentration will be (5.9/1000)x100 = 0.59%
Which gas has increased in concentration by about 0.011 percent in the past 150 years?
Carbon Dioxide
If you have a cell with water concentration of 90 percent and solute concentration of 10 percent and you place it into a solution that is 80 percent water concentration and 20 percent solute concentra?

Why does the percent ionization of acetic acid increase as the concentration of the solution decreases?
As you increase the concentration of the solution, the concentration of H+ does not change. Meaning, the concentration ionized does not change. Just the original concentration increases. Since percent ionization = (concentration ionized)/(original concentration) , and the original concentration is increased, the percent ionization therefore decreases.
What element has the greatest percent of the concentration and what is the percent?
gold at 13%
What is the highest concentration 0.003 percent 0.01 percent or 0.03 percent?
0.03 percent, obviously!
Descriptively what reaction is caused by mixing 98 percent concentration sulfuric acid 50 percent concentration caustic soda?
BOOM!
What is the concentration of oxygen in air?
21 percent.
Dilute a solution which has an initial concentration of 10 percent down to 2 percent?
Calculating concentration of a chemical solution is a basic skill all students of chemistry must develop early in their studies. What is concentration?
What is the difference between 3.8 percent sodium citrate concentration and 3.2 percent?
Presumably, 0.6 percent.
If 2 percent glucose solution and 5 percent glucose solution are separated by a semipermiable menbrane flows from the 2 percent glucose solution to the 5 percent glucose solution?
Yes, during process of osmoses the solvent from higher concentration to lower concentration moves through semipermeable membrane, the 2% solution has lower concentration of solute therefore higher concentration of solvent.
What is percent by mass and percent by volume?
Percent per mass example: uranium concentration in granite is approh. 4 mg/kg. Percent per volume: uranium concentration in ocean water is approx. 4 micrograms/L.
