To get 0.15 moles of NaCl,
mass of NaCl = moles * molar mass
= 0.15 * (23+35.5)
= 8.775 g
and 0.15M is 0.15 mole of NaCl in on liter solvent which equals 8.775 g then ypu add solvent up to 1 liter.

The concertration of a water solution of NaCl is 2.48m and it contains 806 g of water How much NaCl is in the solution?
117 grams of NaCl
How much gNacl and how much gwater needed for ready of 500g solution of NaCl 0.95 percent?
0.95% * 500 g = 4.75 g NaCl
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.
You want 1 liter of 0.1 M NaCl and you have 4 M stock solution How much of the 4 M solution and how much dH2O will you measure out for this dilution?
25ml of the 4M stock solution used
How much nacl is required for a 200 mM NaCl solution?
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.
How much sodium chloride needed to make 10ppm sodium solution?
2.5 g of Nacl is to be dissolve in 100ml of water gives 10ppm of Na solution.
If Julie had a 2.5 molar solution of nahco3 and needed to make 50 ml of a 1.0 m solution how much nahco3 and water would she need?
2.5gm require 100ml of solution 100ml solution require 2.5gm 50ml require 50x2.5/100=1.25ml
What is the molarity of sodium sulphate in a solution prepared by dissolving 15.5g in enough water to make 35ml of solution?
Molarity = moles of solute/volume of solution Find moles NaCl 55 grams NaCl (1mol NaCl/58.44 grams) = 0.941 moles NaCl Molarity = 0.941 moles NaCl/35 Liters = 0.027 Molarity NaCl ( sounds reasonable as 55 grams is not much in 35 Liters of water, which would be about 17.5 2 liter sodas )
How much NaCl is required for 100 mM NaCl solution?
For 100 mM NaCl solution in 1L: Formula weight: 58.44 g/L Answer: 5.844 g/L if you want in 500 mL---2.922 g if you want in 250 mL---1.461 g if you want in 100 mL---584.4 mg
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.
Sodium chloride 0.9 1000ml contains how much sodium chloride?
0.9% means there is 0.9 grams NaCl per 100ml of solution. So 1000 ml of 0.9% sodium chloride contains 9.0 grams of NaCl.
How many molecules of NaCl are in the 1 M NaCl solution?
It depends on how much solution you have!"1 molar solution" means that 1 litre of the solution contains 1 mole of solute (in this case, Na+ and Cl- ions). Therefore, 1 litre of 1M NaCl will contain 1 mole of sodium chloride. 1 mole is avagadro's number (6.02x1023) of a substance. If you have two litres of solution, obviously, you will have twice this number, for example.Note, though, that there are NO molecules of sodium chloride - sodium chloride is not a molecular substance.
