Question

four measuring cylinder with least count 1.0 ml 0.5 ml 0.2 ml and 2.5 ml are given which one among the following is suitable for finding density of a solid

Answer 1

1. Least count is the smallest value that can be measured accurately by the given instrument

2. For the accurate measurement , the cylinder with minimum value of least count is preferable.

3. Answer : 1ml

Answer 2

Out of the given two measuring cylinders of least count of 1.0 ml and 2.5ml respectively, I will prefer the cylinder with the least count of 1.0 ml.

Since it is the smallest value that the 1.0 ml cylinder can measure accurately.

Therefore the cylinder with the minimum least count will be suitable and accurate to measure the density of solid.
