Molalityis the number of moles of solute per kilogram of solvent. Because the density of water at 25°C is about 1 kilogram per liter, molality is approximately equal to molarity for dilute aqueous solutions at this temperature. This is a useful approximation, but remember that it is only an...
0.004564 mol NaOH * (1 mol H+ / 1 mol NaOH) = 0.004564 mol H+ Determining the moles of Ca+2 ions present: 0.004564 mol H+ * (1 mol Ca+2 / 2 mol H+) = 0.002282 mol Ca+2 Detemining the amount of Ca+2 in grams (it was said in the experiment to assume the weight molecular...

Using a standard state in which there are 1,000 g of water (55.51 moles) per 1,000 cm 3 of solution allows activity of water in a NaCl solution at high temperature to be closely approximated by the effective density of water, p e, in that solution, i.e. the product of the density...
