Question

The given graduated cylinder is calibrated in

Answer 1

Answer : The volume of liquid in graduated cylinder is 26.5 mL.

Explanation :

As we know that for the measurement of the volume of liquid in graduated cylinder are shown by placing the graduated cylinder on the flat surface and then view the height of the liquid in the graduated cylinder with the naked eyes directly level with the liquid.

The liquid will tend to curve downward that means this curve is known as the meniscus.

In the case of colored liquid, we are always read the upper meniscus of the liquid for the measurement.

In the case of colorless liquid, we are always read the lower meniscus of the liquid for the measurement.

In the given image, there are 10 division between the 20 and 30 and the solution is colorless. So, we will read the lower meniscus of the liquid for the measurement.

Hence, the volume of liquid in graduated cylinder is 26.5 mL.

Answer 2

Answer: 26mL

Explanation:

You always need to see the meniscus of the liquid, (which is the curved figure in the liquid) in the cylinder, also, the question is telling you that write the correct number of significant figures, as the cylinder does not point at any decimal number, you cannot tell if it is on 26.1 or 26.9, you can be certain, only, that is 26 mL.
