Question

The solubility of MnSO4 monohydrate in water at 20 °C is 70.0 g per 100.0 mL of water. A solution at 20 °C that is 4.22 M in MnSO4 monohydrate is best described as a(n) ________ solution. The formula weight of MnSO4 monohydrate is 168.97 g/mol.

solvated

saturated

supersaturated

hydrated

Answer 1

70 g Mn S04 molar mass of Mn S04 = 168.97 g/mol 100 mL of water = 0.14 walie 1:1 m2 = 10-31) moles of MnSO4 = mass of MnS04 molar mass of MnSO4 = 70g = 0.4143 mol 168.97 g/mol Molarity = number of moles uslume of solution in i = 0.414 3 mol = 4.143 M 0.11 : 4.22 M > 4.143 M :. A solution that is 4.22 Min Mn 504 monohydrate is best described as an superaturated solution
