Calculate the qsp or ksp, as indicated, and determine whether a precipitate will form when each of the following mixtures is prepared. (you may assume temperature is held constant, volumes are additive, and that the initial solutions, prior to mixing, are unsaturated.) (a) 25.30 ml 1.48 ✕ 10−4 m cacl2 is mixed with 25.16 ml 3.02 ✕ 10−3 m naf. (ksp for caf2

1. for the first question, we must find the mass of the anhydrous salt, mgso₄. the molar mass for mgso₄·7h₂o is 246.47 g/mol, while that of mgso₄ is 120.37 g/mol.7.834 g mgso₄·7h₂o * 1 mol mgso₄·7h₂o/246.47 g * 1 mol mgso₄/1 mol mgso₄·7h₂o * 20.37 g mgso₄/mol = 0.647 g mgso₄

2. mass of water = mass of sample - mass of anhydrous salemass of water = 7.834 - 0.647 = 7.19 gpercent water in hydrate = 7.19/7.834 * 100 = 91.74%
