Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
If you wanted to measure our 15 mL of salt water for an experiment, which would be your best choice for an accurate measurement?
A
measuring cup
B
beaker
C
graduated cylinder
D
test tube
Explanation: 

Detailed explanation-1: -When measuring small amounts of capacity, you can use a graduated cylinder. Graduated cylinders can measure milliliters and centiliters.

Detailed explanation-2: -The volume measurements we make using a 10-mL graduated cylinder are more precise as compared to measurements done by using 100-mL graduated cylinder. In case of 10 mL graduated cylinder, tenth of a milliliter is the smallest graduation (0.1) and can take approximation to the hundredths place (0.01).

Detailed explanation-3: -Most 50 ml graduated cylinders have markings spaced every milliliter while 10 ml graduates have markings every tenth of a milliliter. If we measure a small volume of liquid in a 10 ml graduate, our measurement should be more accurate than if a 50 ml graduate were used.

Detailed explanation-4: -If you look at a 10mL graduated cylinder, for example, the smallest graduation is tenth of a milliliter (0.1mL). That means when you read the volume, you can estimate to the hundredths place (0.01mL). Use the bottom of the meniscus to determine the volume in the 10mL graduated cylinder.
