Record the measurement to the
correct number of significant figures. ( PUT UNITS IN
ANSWER, FOR EXAMPLE - 851 mL)
Homework Answers
To record the volume from graduated cylinder draw a tangent to the meniscus of the liquid and took the reading. Here the least count is 1mL. So either we can accurately measure it 36mL or 37 mL. The meniscus lies middle between them.
So for to take significantly we should consider the lower limit means, it should be recorded as 36mL.
