A plant loses 0.12 g of water in 30 minutes. Calculate the rate of transpiration in milligrams per minute.
Answer
4 mg per minute
The correct answer is 4 mg per minute — State the rate as 4 mg per minute.
Step-by-step solution
- Convert the mass lost from grams to milligrams: 0.12 g = 0.12 × 1000 = 120 mg.
- Divide the total loss by the time in minutes: 120 mg ÷ 30 min = 4 mg/min.
- State the rate as 4 mg per minute.
Common mistake: Forgetting to convert grams to milligrams
Concept tested: Rate calculation of transpiration
