To prepare a 100 mM NaCl solution, you would need to calculate the molecular weight of NaCl, which is approximately 58.44 g/mol (sodium's atomic weight is 22.99 g/mol and chlorine's is 35.45 g/mol). To make a 100 mM solution, you would need 0.1 moles of NaCl per liter of solution. This would be equivalent to 5.844 grams of NaCl per liter of solution.
What else can I help you with?
What is the mass percent of the solution. if An aqueous NaCl solution is made using 138 g of NaCl diluted to a total solution volume of 1.10 L Assume a density of 1.08 g per ml for the solution.?
The mass of the solution is the sum of the mass of NaCl and the mass of water. First, we calculate the mass of the solution by multiplying the density by the volume: 1.08 g/mL * 1100 mL = 1188 g. The mass percent of NaCl in the solution is then found by taking (mass of NaCl / mass of the solution) * 100%: (138 g / 1188 g) * 100% = 11.62%.
What is the concentration in mm percent of a solution prepared from 50.0g Na-Cl and 150.0g of water?
To find the concentration in mass percent, first calculate the total mass of the solution (50.0g NaCl + 150.0g water = 200.0g total). Then, divide the mass of NaCl by the total mass of the solution and multiply by 100 to get the concentration in mass percent: (50.0g NaCl / 200.0g total) * 100 = 25.0% NaCl.
What is the normality of the solution which is prepared by the adding 100g NACL in 1 liter of solution?
For NaCl [note correct capitalization], normality is the same as molarity, the number of moles or, for ionically bonded compounds such as NaCl, gram formula masses per liter of solution, because the ions produced from NaCl in water are monovalent. The gram formula mass of NaCl is 58.44. Therefore 100 g of NaCl constitute 100/58.44 or 1.71 gram formula masses, to the justified number of significant digits. If the final volume of the solution is 1 litre, this is also the normality. If the volume is not considered exact, only one significant digit would be justified for normality, which should then be specified as 2.
How do you find molarity of NaCl in a saturated solution?
Saturated is 36 - 40 g / 100 mL : Divide grams by the molar mass 58.5 g/mol NaCl and you'll find mol/100 mL Multiplying this value by 10 (= dL/L) and you find mol/L. Doing an estimation gives me approx. 7 mol/L, my calculator is tilted, so I hope your's doing better.
Does the Mass mass percent concentration measures grams of solute per grams of solvent?
No, not exactly.Mass mass percent concentration measures grams of solute per 100 grams of solution (= solvent + solute)Example:58.5 g NaCl (solute) added to941.5 g H2O (solvent) gives you1000.0 g solution of 5.85% NaCl (= 100%*58.5/1000.0),which is about a 1.0 mol/L NaCl solution.
What is the concentration of NaCl in a solution that contains 0.9 NaCl?
The concentration of NaCl in a solution that contains 0.9 NaCl is 0.9 grams of NaCl per 100 grams of solution.
Is 100 ppm solution of NaCl means 100 ppm of Na?
No, a 100 ppm NaCl solution means there are 100 parts per million of NaCl (sodium chloride) in the solution, not just sodium (Na) alone. To calculate the amount of sodium ions (Na+) in the solution, you would need to consider the molar mass of NaCl and the percentage of Na+ in NaCl.
What is the mole fraction of 18 mol NaCl in a solution of 100 mol water?
The mole fraction of NaCl in the solution is calculated by dividing the moles of NaCl by the total moles of NaCl and water. In this case, the mole fraction of 18 mol NaCl in a solution of 100 mol water is 0.15 (18 mol NaCl / (18 mol NaCl + 100 mol water)).
Saline is what percent NaCl?
If you think to an isotonic solution the concentration is 0,9 g NaCl/100 g solution.
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 percent of NaCl in solution with 59mg of NaCl in 375ml water?
The concentration of NaCl is 15,73 mg/100 mL.
Determine how much of each of the following NaCl solutions in grams contains 1.5g of NaCl 0.058 percent NaCl by mass?
In order to determine this, it is necessary to know what solution we are looking at. One we know that we can look at the grams in a mole of the substance and determine the percentages based on molecular weight.
What is the mass percent of NaCl when 6.5g of NaCl dissolves with 250g of water?
This concentration of NaCl is 2,6 g NaCl/100 mL solution.
How do you prepare a solution 2 percent NaCl wv?
To prepare a 2% NaCl (w/v) solution, you would dissolve 2 grams of NaCl in enough water to make 100 mL of solution. This means you would add 2 grams of NaCl to a flask and then add water until the total volume reaches 100 mL.
How do you calculate 100 ml of 0.9 percent NaCL?
To prepare a 0.9% solution take 0.9grams NaCl and dilute with 100mls of water.
How do you prepare a 30 percent NaCl solution?
Oh honey, it's not rocket science. Just measure out 30 grams of table salt and dissolve it in enough water to make 100 grams of solution. Voila, you've got yourself a 30% NaCl solution. Just don't go drinking it thinking it's a margarita, okay?
How do you prepare approximately 100 ml of 1.0 m NaCl?
To prepare 100 ml of 1.0 M NaCl solution, you would need to dissolve 5.84 g of NaCl in enough water to reach a final volume of 100 ml. Measure out the required amount of NaCl, add it to a beaker, and then add water while stirring until the final volume reaches 100 ml.
