solubility of NaCl in water at 298K is 35.8 kg per 100 kg of water calculate mass fraction of NaCl?

To calculate the mass fraction of NaCl in a solution, we need to know the mass of NaCl and the mass of water in the solution. In this case, we are given the solubility of NaCl in water, which is 35.8 kg per 100 kg of water at 298K.

To find the mass fraction of NaCl, we can use the following formula:

Mass fraction of NaCl = Mass of NaCl / (Mass of NaCl + Mass of water)

Now, let's calculate the mass of NaCl.

Given that the solubility of NaCl is 35.8 kg per 100 kg of water, we can calculate the mass of NaCl using the following equation:

Mass of NaCl = Solubility of NaCl × Mass of water

Substituting the given values, we have:

Mass of NaCl = 35.8 kg/100 kg × 100 kg

Mass of NaCl = 35.8 kg

Now, let's calculate the mass fraction of NaCl.

Mass fraction of NaCl = 35.8 kg / (35.8 kg + 100 kg)

Mass fraction of NaCl = 35.8 kg / 135.8 kg

Mass fraction of NaCl ≈ 0.264

So, the mass fraction of NaCl in the solution is approximately 0.264.

35.8 kg/100 kg = 35.8g/100g = 0.358 as a fraction.
