Divide the mass of the compound by the mass of the solvent and then multiply by 100 g to calculate the solubility in g/100g . Solubility of NaNO3=21.9g or NaNO3 x 100 g/ 25 g =87.6.

Is molar solubility the same as molarity?

No, solubility and molarity are two different properties.

How do I calculate molarity?

The key to calculating molarity is to remember the units of molarity (M): moles per liter.

To calculate molarity:
Find the number of moles of solute dissolved in solution,Find the volume of solution in liters, and.Divide moles solute by liters solution.

How does molar solubility change with pH?

For ionic compounds containing basic anions, solubility increases as the pH of the solution is decreased. For ionic compounds containing anions of negligible basicity (such as the conjugate bases of strong acids), solubility is unaffected by changes in pH.

What is the Ksp for NaCl?

Ksp for sodium chloride is 36 mol^2/litre^2 .
