Step 2

A pipette is a commonly used laboratory tool. It is mainly used to transfer the measured amount of liquid.  

Each pipette has certain volume and is marked with that value so to measure that volume, it has to fill till that mark.

Step 3

In the determination density of water, mass and volume must be measured. The volume of water is measured through a clean pipette. If after delivery some of the water droplets can be cling to...
