## What is molality of 3m solution of NaCl?

Given: Density of solution = 1.25 g/mL. M =3 mol/lit. Molality of the solution is 2.79 m.

### How do you find the molality of a solution when given the density?

The formula for molality is m = moles of solute / kilograms of solvent. In problem solving involving molality, we sometimes need to use additional formulas to get to the final answer. One formula we need to be aware of is the formula for density, which is d = m / v, where d is density, m is mass and v is volume.

#### How do you make a 3m solution of NaCl?

3 Molar solution means there are 3 moles of Na Cl salt in 1 Liter. Molecular weight of Na Cl = 58.44. Hence, there are 3 * 58.44 gms in 1 Litre of water. So 1,074.68 ml or 1, 074.68 gms of water is mixed with 3 moles of Na Cl to make the 3 M solution.

What is the molality of 3m solution of NaCl having a density 1.25 gram per mL the molar mass of NaCl is 58.5 gram per mL?

molality == = 2.791m.

What is the density of NaCl solution?

2.16 g/cm³
Sodium chloride/Density

Crystalline sodium chloride, NaCl(s) has a higher density than water at 2.165 g/mL. The density of any NaCl solution will be greater than that of pure water but, as we saw above, the density is close to that of pure water.

## What is the molarity of NaCl solution having 1.52 ppm?

Since every mole of NaCl contains one mole of sodium, the number of moles of NaCl present per litre of the solution is equal to 6.6*10^-5. Therefore, the molarity of NaCl is equal to 6.6*10^-5 M.
