You need the density. 1.8% NaCl (by mass or w/w) means 1.8 g NaCl/100 g solution. 1.8g NaCl/molar mass NaCl = moles NaCl. Then 100 g solution converted to mL from the density. volume = 100 g/density and convert mL to L. M = moles/L.

50 ppm = 50 g NaCl/10^6 g water and since the density of the solution is so close to 1.00 we will call that 50 g NaCl/10^6 mL = 0.050 g NaCl/L. Convert g NaCl to moles.

I would do this. 3.5% NaCl by mass means 3.5g NaCl/100 g solution. The density of th solution is 1.02 g/mL; therefore, the 100 g soln has a volume of mass/density = 100g/1.02 = 98.04 mL. Next, I would convert 3.5 g NaCl to g Na. That is easily done by 3.5g NaCl x (molar mass ...

The solubility of NaCl in water is 35.7 g NaCl/100 g H2O. Suppose that you have 500.0 g of NaCl. What is the minimum volume of water you would need to dissolve it all? The density of water is 1.0 g/mL.

I have a certain concentration of NaCl (in mg/L). I have to convert it to ppm Na+. I read some of the previous posts, and I understand that if I don't know the density, I should assume that 1ppm = 1mg/L. Does this also apply to ppm Na+ since there is 1 Na+ ion for each ...

NaCl dissociates completely in water. Therefor the total number of particles in a 1.0 m NaCl solution is no longer 6.02 X 10^23. Since a colligative property is dependent only on the total number of solute particles, what is the freezing point for 1.0 m NaCl solution?

0.5% NaCl w/v means 0.5 g NaCl in 100 mL solution. For 375 mL you will need 0.5 g NaCl x (375/100) = xx g NaCl. This assumes that adding 0.5 NaCl to 100 mL water will not increase the volume.

Molarity is about as simple as it gets. The definition is all you need. The definition of molarity is Molarity = M = # moles/Liter of solution. So, to prepare a 1 molar solution, of something, say NaCl, you dissolve 1 mole of NaCl in water, shake it around until all of it ...
