Step 1: Place an empty container or weigh boat on the balance.
We denote the mass of the container as $m_{container}$.
This step is necessary to tare the balance, which means setting the current weight to zero. This way, you can accurately measure the mass of the sample without including the weight of the container.
Step 2: Use the tare function on the balance to cancel out the mass of the container.
The tare function is usually found on digital balances and allows you to subtract the weight of the container from the total weight. After taring, the balance should read zero. Mathematically, taring the balance can be represented as:
Final Answer
To use the tare function on a balance, place an empty container on the balance, use the tare function to cancel out the container's mass, and then place your sample in the container and record the mass.
