How would 300 mL of a 0.9 percent sodium chloride solution be prepared using sodium chloride crystals?
1. Dry some 5-6 grams of sodium chloride in an oven at 110 0C for 30 min.
2. Place the crucible with the salt in a desiccator for 30 min.
3. Weight on an analytical balance 4,5 g of NaCl sodium chloride.
4. Transfer quantitatively the salt in a 0,5 L volumetric flask.
5. Add 450 mL distilled (or demineralized) water in the flask.
6. Put the flask in a thermostat at 20 0C for 30 min.
7. Add distilled (or demineralized) water in the flask to the mark.
8. Transfer the solution in a tightly stoppered bottle.
9. Add a label with the name of the solution, concentration, data, name of the operator.

What is the mass percent of sodium chloride in a solution prepared by adding 1 g of sodium chloride to 50 g of water?
The mass percent of sodium chloride can be calculated as follows: Mass of NaCl = 1 g Mass of water = 50 g Total mass of solution = 1 g + 50 g = 51 g Mass percent of NaCl = (Mass of NaCl / Total mass of solution) x 100% = (1 g / 51 g) x 100% ≈ 1.96%
What is the percent of a water solution that contains 60 g of calcium chloride and that has a mass of 400 g?
The percent of a solution is calculated by dividing the mass of the solute by the mass of the solution and multiplying by 100. In this case, the percent of the water solution containing 60 g of calcium chloride in a 400 g solution would be (60 g / 400 g) * 100 = 15%.
What is the percent by mass of the solute sodium hypochlorite is 5.24 percent you have a 2500.0 grams of bleach solution. How many grams of NaCl are in the solution?
If the percent by mass of sodium hypochlorite (NaClO) in the bleach solution is 5.24%, then 100% - 5.24% = 94.76% is the water weight. For a 2500.0g solution, the mass of NaClO is 5.24% of 2500g = 131g. Since the remaining mass is water, the mass of NaCl (sodium chloride) in the solution would be zero.
How much grams of ferric chloride to be added in 100ml of water to get 2 percent solution?
To prepare a 2% solution of ferric chloride in 100ml of water, you would need to add 2 grams of ferric chloride. This is calculated by multiplying the volume of the solution (100ml) by the desired concentration (2%) and converting it to grams.
What is the percent by weight of NaCl in a saturated solution of sodium chloride at 50 degree Celsius?
The percent by weight of NaCl in a saturated solution at 50 degrees Celsius is approximately 26.3%. This means that in every 100 grams of the solution, 26.3 grams is NaCl.
What is the mass percent concentration of the solution prepared by adding 20 g of sodium chloride into 380 g of water?
Divide the amount of sodium chloride by the total amount (sodium chloride + water). Then multiply that by 100 to convert to percent.
Why is sodium chloride 0.9 percent percent given?
This is a isotonic saline solution.
Which has the highest conductivity between sodium chloride crystal and 5 percent sodium chloride solution?

Why1.2 percent water solution of potassium chloride used in UV calibration?
The solution of potassium chloride is used to evaluate the stray light.
How many moles of sodium chloride solute are in 155 grams of an 85.5 percent by mass solution?
To find the moles of sodium chloride solute in 155 grams of an 85.5% solution, first calculate the mass of sodium chloride present in the solution (mass percent x mass of solution). Then, convert the mass of sodium chloride to moles using its molar mass (58.44 g/mol). This will give you the number of moles of sodium chloride solute in the solution.
What is the mass percent of sodium chloride in a solution prepared by adding 1 g of sodium chloride to 50 g of water?
The mass percent of sodium chloride can be calculated as follows: Mass of NaCl = 1 g Mass of water = 50 g Total mass of solution = 1 g + 50 g = 51 g Mass percent of NaCl = (Mass of NaCl / Total mass of solution) x 100% = (1 g / 51 g) x 100% ≈ 1.96%
What is Sodium chloride 0.9 percent?
This is an isotonic saline solution; 9 g/L sodium chloride solution in water with added glucose.
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.
Are Sodium Chloride 0.9 percent and Normal Saline the same solution?
Yes, Sodium Chloride 0.9% and Normal Saline are the same solution. Normal Saline is a sterile solution of 0.9% sodium chloride in water, commonly used in medical settings for hydration and to dilute medications.

This solution contain 5 g NaCl dissolved in water.
What is the percent of a water solution that contains 60 g of calcium chloride and that has a mass of 400 g?
The percent of a solution is calculated by dividing the mass of the solute by the mass of the solution and multiplying by 100. In this case, the percent of the water solution containing 60 g of calcium chloride in a 400 g solution would be (60 g / 400 g) * 100 = 15%.
