Osmolar clearance (Cosm) is calculated using the formula: Cosm = (Uosm * V) / Posm, where Uosm is urine osmolality, V is urine volume per minute, and Posm is plasma osmolality. First, convert urine volume to mL/min: 720 mL / 1440 min = 0.5 mL/min. Then, Cosm = (700 mOsm * 0.5 mL/min) / 300 mOsm = 350 / 300 = 1.1667 mL/min, which rounds to 1.2 mL/min.
