Question

when using the tare function on a balance, start by choose... then, choose... to cancel out that mass. finally, choose... and record the mass of your sample. choose... press the tare/zero button place the glassware on the balance add your sample to the glassware

Explanation:

To use the Tare function on a balance:

1. First, place the glassware (like a beaker or flask) on the balance. This is the container that will hold the sample, and we need to account for its mass initially.
2. Then, press the Tare/Zero button. This function resets the balance's reading to zero, effectively canceling out the mass of the glassware. So the balance now only measures the mass added after this step.
3. Finally, add your sample to the glassware. Now, the balance will display the mass of just the sample (since the glassware's mass was tared out), and you can record that mass.

So the first "Choose..." should be "place the glassware on the balance", the second "Choose..." (next to "start by") should be "press the Tare/Zero button" (wait, no, let's re - order:

Wait, the sequence is:

Start by placing the glassware on the balance (this is the first action - putting the container on the balance). Then, press the Tare/Zero button to cancel out the mass of the glassware. Finally, add your sample to the glassware and record the mass of the sample.

Let's confirm the steps of using a balance with tare:

1. Place the empty container (glassware) on the balance pan.
2. Press the tare button to zero the balance (so the balance now ignores the container's mass).
3. Add the sample to the container, and the balance will show the mass of the sample.

So filling in the blanks:

First dropdown (start by): place the glassware on the balance

Second dropdown (then, to cancel out that mass): press the Tare/Zero button

Third dropdown (finally, and record the mass): add your sample to the glassware

Answer:

First "Choose...": place the glassware on the balance
Second "Choose...": press the Tare/Zero button
Third "Choose...": add your sample to the glassware
