What is the concentration of 58.5g of NaCl in 2 L of solution?
0.494 M
How could you make a 1.00M solution if you had a 2.00M solution of NaCl?
If we add 1 L of water to 1 L of 2 M NaCl solution will give 2 L of 1 M NaCl solution
2 Predict and explain what systems are electrically conducting a solid NaCl b molten NaCl c An aqueous solution of NaCl?
molten NaCl and An aqueous solution of NaCl will be conducting due to the presence of free ions in these.
A solution is made by dissolving 17.52g of nacl exactly 2000 ml what is the molarity of this solution?
concentration or molarity = number of moles/volume number of moles (n) = mass in grams of nacl/relative atomic mass of nacl n=17.52/(23+35.5) n = 0.2994872 mol volume = 2000/1000 = 2dm^3 molarity = 0.2994872/2 =0.15mol/dm^3
How many ions present in NaCl solution?
2 Sodium and Chloride.

Is 10 percent of NaCl isotonic?
No, it is far from isotonic. there's even more salt in it than in ocean water (3%).A typical home recipe for an isotonic solution, used for nasal spray, consists of 1⁄2 litre of water, 4 to 5 grams (1 teaspoon) of salt. This is about 10 grams per Litre or 1 % NOT 10%
How many milliliters of 2 M NaCl solution are required to make 1 liter of 0.4 M NaCl solution?
200 milliliters
How many grams of NaCl are in a 2 percent NaCl solution?
That refers to a mixture consisting of 2/100 of sodium chloride (salt) and 98/100 of something else (usually water).
What is the pH of a hydrogen solution that has a hydrogen concentration of 10-2?
If concentration of Hydrogen in solution is 10-2 then its pH must be 2.
How much 2M Nacl solution would you need to make 250ml of 0.15M Nacl solution?
By the definition of molarity, which is mass of solute in moles divided by solution volume in liters, 250 ml of 0.15 M NaCl* solution requires (250/1000)(0.15) or 0.0375 moles of NaCl. Each liter of 2M NaCl solution contains 2 moles of NaCl. Therefore, an amount of 0.0375 moles of NaCl is contained in (0.0375/2) liters, or about 18.75 ml of the 2M NaCl, and if this volume of the more concentrated solution is diluted to a total volume of 250 ml, a 0.15 M solution will be obtained. _________________ *Note correct capitalization of the formula.

How much NaCl precipitate would be produced if 2 molarity HCl and 1 molarity sodium carbonate react in the reaction Na2CO3 plus 2HCL yeilds 2NaCl plus H2O plus CO2?
The resulting product would be a roughly 2 M NaCl solution (slightly less than 2 molar because the solution is diluted by the water that is produced by the reaction). 2 M HCl + 1 M Na2CO3 --> 2 M NaCl + 1 M H2O + 1 M CO2 Two moles of NaCl weigh about 117 g (58.5 grams per mol) so the resulting solution has a sodium chloride concentration of about 117 grams per liter. This concentration is well below the maximum solubility of water at room temperature and atmospheric pressure ( > 300 g/liter) so there would not be any NaCl at all precipitating. The answer is thus: no NaCl precipitate will form.
Is 2 percent NaCl hypotonic or hypertonoic?
This is a hypertonic solution.
How do you calculate the molarity of the solution of 17.52 grams of Na Cl in a total volume of 2000 ml of solution?
Need moles NaCl first. 17.52 grams NaCl (1 mole NaCl/58.44 grams) = 0.29979 moles NaCl =====================Now. Molarity = moles of solute/Liters of solution ( 2000 ml = 2 Liters ) Molarity = 0.29979 mole NaCl/2 Liters = 0.1499 M NaCl ----------------------
