Divide the amount of sodium chloride by the total amount (sodium chloride + water). Then multiply that by 100 to convert to percent.

What is the percent mv of a water solution that contains 60 g of calcium chloride CaCl2 and that has a volume of 400 mL?
The percent mv is 6.7%.
Are Sodium Chloride 0.9 percent and Normal Saline the same solution?
Sodium chloride 0.9 percent and normal saline are not quite the same solution. While they share the same osmolality, sodium chloride contains more salt.
Can 0.9 percent sodium chloride solution be used in eyes?
Yes
How do make a percent sucrose solution?
Calculate the weight of sucrose for the desired volume and concentration of the solution.
A solution contains 30 g of calcium chloride in 250 g of water express the mass percent?
The solution has a total mass of 30 + 250 = 380 g. The mass percent of calcium chloride in this solution is 100(30/380) = 7.9 %, to the justified number of significant digits.
What is the percentage by mass of salt solution prepared by dissolving 11 grams of salt in 80 grams of solution with solution?
The percent concentration is 13,75 %.
How can you express the concentration of a substance mathematically?
In chemistry, the concentration of a substance in solution is determined by molarity, which is symbolized by "M". This indicates the number of moles of a substance dissolved in one liter of a solvent (usually water). For example: - 1 mole of sodium chloride = 58 grams - If 116 grams of sodium chloride are dissolved in 1 liter of water, then that solution is a 2-molar (2 M) solution of sodium chloride. - If 232 grams of sodium chloride are dissolved in 1 liter of water, then that solution is a 4-molar (4 M) solution of sodium chloride.
What is the mass percent of sodium chloride in a solution prepared by adding 1 g of sodium chloride to 50 g of water?
100[1/(50 + 1)] = 2 %, to the justified number of significant digits.
What is the concentration in mm percent of a solution prepared from 50.0g Na-Cl and 150.0g of water?

What is meant by the mass mass percent concentration of a solution?
This is (mass of solute) divided by (mass of total solution) expressed as a percentage. The solute is what you are dissolving into the solution. Example: you have 90 grams of water, and you add 10 grams of salt (sodium chloride). The water is the solvent, sodium chloride is the solute, and the solution is salt water. 90 grams + 10 grams = 100 grams (mass of total solution). (10 grams) / (100 grams) = 0.1 --> 10% mass mass percent concentration.
What is the percent mv of a water solution that contains 60 g of calcium chloride CaCl2 and that has a volume of 400 mL?
The percent mv is 6.7%.
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.
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 percent of sodium in a salt water solution?
The concentration may be very variable; at 20 0C the solubilty of sodium chloride in water is approx. 360 g/L.
Why is sodium chloride 0.9 percent percent given?
This is a isotonic saline solution.
