Question

A solution is made by dissolving 1.00 g of the ligand salen (C16H16N2O2) in enough water to make to make 1.00 L of solution. Determine the concentration of the resulting solution.

Answer 1

Molar mass of ligand salen C16H16N2O2 is 268.3104 g/mol

1 gm of ligand salen ×1 mol of ligand salen / 268.3104 g/mol = 0.0037 mol

Molarity = 0.0037 mol of ligand salen / 1.0 lit solution = 0.0037 M

Concentration of the solution is 0.0037 M
