Question 3b
Calculate how much urine was produced in the two hours after drinking the litre of water. [1]
Answer:
Using the corrected values from the graph:
- Urine output in the first 30 minutes: 20 cm³
- At 1 hour: 350 cm³
- At 1.5 hours: 500 cm³
- At 2 hours: 280 cm³
Total urine produced in 2 hours:
20 + 350 + 500 + 280 = 1150 cm³
Answer: The total urine produced in the two hours after drinking the litre of water is 1150 cm³.
