What is the relative uncertainty of 100 ml measured in this beaker? In assessed a level practical tasks, the mean of two titres of 25.25 cm3 and 25.20 cm 3.
25 Ml Beaker Uncertainty. What is the relative uncertainty of 100 ml measured in this beaker? Percentage error = (2 × 0.05) ÷ 25.00 = 0.004 × 100 = 0.4% page 11 10 for small volumes, the percentage error becomes more significant for delivery of 2.50 cm3, the percentage error would be:
