Web15 Oct 2024 · When read from the lowest point of the meniscus, the correct volume reading is 30.0 mL. The first 2 digits 30 .0 are known exactly. The last digit 30. 0 is uncertain. Even though it is a zero, it is significant and must be recorded. The volume of a solid must be measured indirectly based on its shape. WebA. If something require a measurement on both sides of something (like a ruler) then you are correct +-0.5mm but on both sides so this makes the total uncertainty +-1mm. Another example of this is a stop watch, you have uncertainty at the start and at the beginning for the uncertainty will be +-0.01 s (if this is the resplution of the stop ...
