Step 2: Why do you want to design a jade bracelet like this? I don't understand. What is the reason? How to calculate this? Please elaborate ~

This design is definitely wrong. First of all, 82 is the quality of cups and water. The quality of the jade bracelet itself is problematic. Then pour out the water. There is still water in the water, so this error is not allowed in the experiment. So there is something wrong with the preemptive right. If you emptied the water, why did you take it away? This is the third question. The final formula is also wrong. 82g is not the mass of pure overflow water. Take the weight of beaker and water and divide it by the density of water. I thought you were joking.

The correct experimental steps are as follows.

You can measure the quality of the jade bracelet first.

Then measure the mass of the small beaker.

Then receive the spilled water, and then measure the mass of the small beaker filled with water.

As soon as the two are reduced, the quality of overflow water can be obtained. Divide by density to get the volume.

Then divide the initial mass of the jade bracelet by the volume of water, and the density of the jade bracelet can be obtained.
