To determine the amount of NaCl in the solution, you first need to calculate the moles of NaCl present. Using the given molarity (2.48 M) and the volume of the solution (assumed to be 806 g = 806 ml for water), you can find the moles of NaCl. Then, you convert the moles of NaCl to grams using the molar mass of NaCl (58.44 g/mol) to find the amount of NaCl in the solution.
To determine the grams of NaCl in 0.058% NaCl solution, you first convert 0.058% to a decimal by dividing by 100 (0.00058). Then, you set up a proportion to find out how much of the solution contains 1.5g of NaCl. 1.5g of NaCl is equivalent to 0.00058x, where x is the total grams of solution. Solve for x to find how much of the solution is needed.
0.95% * 500 g = 4.75 g NaCl
To make 1 liter of 0.1 M NaCl solution, you will need 25 ml of the 4 M NaCl stock solution and 975 ml of water. This will give you the desired concentration of 0.1 M NaCl in a total volume of 1 liter.
To prepare 250 ml of 0.15M NaCl solution, you would need 10 ml of 2M NaCl solution. This can be calculated using the formula: (C1V1 = C2V2), where C1 is the initial concentration, V1 is the initial volume, C2 is the final concentration, and V2 is the final volume.
You need 58,44 mg of ultrapure NaCl; dissolve in demineralized water, at 20 0C, in a thermostat, using a class A volumetric flask of 1 L.
To find the volume of 0.075 M NaCl solution that can be made, you can use the formula C1V1 = C2V2. Plugging in the values, we get (9.0 M)(450 mL) = (0.075 M)(V2). Solving for V2 gives V2 = 1.1 L. Therefore, 1.1 L of 0.075 M NaCl solution can be made by diluting 450 mL of 9.0 M NaCl.
2.5 g of Nacl is to be dissolve in 100ml of water gives 10ppm of Na solution.
To prepare a 100 mM NaCl solution, you would need to dissolve 5.84 grams of NaCl in water to make a final volume of 1 liter. This calculation is based on the molar mass of NaCl (58.44 g/mol) and the definition of molarity (Molarity = moles of solute / volume of solution in liters).
To find the molarity of the solution, first calculate the number of moles of sodium sulfate by dividing the mass (15.5g) by the molar mass of sodium sulfate (142.04 g/mol). Next, convert the volume of the solution to liters (35 ml = 0.035 L). Finally, divide the number of moles by the volume in liters to get the molarity of sodium sulfate in the solution.
No, the elevation in boiling point will not be the same for a 0.1 m NaCl solution and a 0.1 m sucrose solution. This is because the elevation in boiling point is directly proportional to the number of particles in the solution, known as the van't Hoff factor. NaCl dissociates into two ions (Na+ and Cl-) in solution, so it has a van't Hoff factor of 2, while sucrose does not dissociate and has a van't Hoff factor of 1. Therefore, the NaCl solution will have a greater elevation in boiling point compared to the sucrose solution.
The freezing point depression can be calculated using the formula: ΔTf = i * Kf * m, where i is the van't Hoff factor (number of particles), Kf is the cryoscopic constant, and m is the molality of the solution. Given that i for NaCl is 2, and assuming Kf for water is 1.86 °C/kg/mol, the ΔTf for a 4 mol NaCl solution in 1 kg of water can be calculated.
