Answer:
The lowest and highest possible volumes of the pipette measurement is the slight change in the measured value due to the error value. Hence, the lowest and highest possible values are 0.195cm³ and 0.205cm³ respectively
Explanation:
Given the Parameters :
Measurement uncertainty = 0.01 cm³
Error = uncertainty value /2 = 0.01/2 = 0.005 cm³
Measured volume = 0.20 cm³
Possible values = measured value ± Error
Lowest possible value = 0.20 - 0.005 = 0.195 cm³
Highest possible value = 0.20 + 0.005 = 0.205 cm³
Therefore, the lowest and highest possible values are 0.195cm³ and 0.205cm³ respectively.
