If you fill 12 trays with water and find the total water mass to be 500 g, the quickest way to figure out the mass of water in one of the trays would be to divide the total mass of water by 12.
Since the total mass of water in the 12 trays = 500 g
Mass of water in a single tray would be = 500/12
= 41.67 rounded to 2 decimal places.
This represents the quickest way because direct weighing will require a few steps and, thus, takes more time.
For direct weighing:
- One of the trays will first be placed on a weighing balance and its weight tared
- Water will then be poured into the tray to fill and the reading on the weighing balance recorded as the mass of water in one tray.
