Molar mass of Sodium Lactate = 112 g/mol
1 milimol = 10-3 mol
1 milimol of Sodium Lactate = 112 x 10-3 g = 0.112 g = 112 mg
Therefore, 1 milimol/L Sodium Lactate = 112 mg of Sodium Lactate in 1 L.
1000 mL of solution contains Sodium Lactate = 112 mg
100 mL of solution contains Sodium Lactate = 11.2 mg
Hence, mg% concentration of the solution is 11.2 %.
