The Correct Answer and Explanation is :
When using the tare function on a balance, start by choosing the empty container or vessel that will hold your sample. Then, choose the tare button or function to cancel out that mass. Finally, choose the sample you wish to weigh and record the mass displayed on the balance.
Explanation of the Tare Function
The tare function on a balance is a crucial feature that allows for accurate measurement of a sample’s mass without including the weight of its container. The process begins by selecting an appropriate empty container, such as a beaker or weighing boat, that you plan to use to hold your sample.
Once you have placed the empty container on the balance, the next step is to press the tare button. This action effectively resets the balance to zero, subtracting the mass of the container from future measurements. Taring is essential for ensuring that only the mass of the sample itself is recorded, thus improving accuracy and reducing the potential for error.
After the balance has been tared, you can then add your sample to the container. The balance will now display the mass of the sample alone, without the weight of the container included. This is particularly important in laboratory settings where precise measurements are vital, such as in chemical reactions or formulation processes.
Recording the mass of your sample is the final step. It’s important to document this value accurately, as it will be crucial for any subsequent calculations or analyses you need to perform. Additionally, ensuring that the balance is calibrated and placed on a stable surface before use will help maintain accuracy throughout the process.
In summary, the tare function streamlines the weighing process by allowing you to focus solely on the mass of the sample, enhancing precision and reliability in your measurements.
