How to solve molarity problems
WebA compound's molar solubility in water can be calculated from its Kₛₚ value at 25°C. To do so, first prepare an ICE (Initial, Change, and Equilibrium) table showing the equilibrium concentrations of the ions in terms of x, the molar solubility of the compound.Then, plug these expressions into the solubility-product expression for the compound and solve for … WebFor the third solution, we are given the amount of NaCl as 0.0420 mol and the final volume as 6.50 mL. We need to convert the volume to liters before we can use the formula: …
