Igcse Model Questions Vol1 2024 Biology Question 24
Practice objective / multiple choice question 24 from the 2024 Igcse Model Questions Vol1 Biology examination.
The kidneys filter \(180\ \text{L}\) of plasma per day. Plasma osmolality is \(300\ \text{mOsm kg}^{-1}\). The renal tubules reabsorb \(95\%\) of the filtered solutes. The person produces \(1.2\ \text{L}\) of urine per day. Assuming that the urine osmolality equals the amount of solute excreted divided by urine volume, calculate the urine osmolality (in \(\text{mOsm L}^{-1}\)).
