(1) Council of Europe

(2)7 1.2

(3)8.9× 10 3

(1) After analysis, the specific steps of measuring the solid Guanyin pendant in this experiment are as follows:

A, put the tray balance on a horizontal desktop;

B, moving the traveling code to the zero scale line of the scale, and adjusting the balance nut on the cross beam to balance the cross beam in a horizontal position;

D, placing the pendant in the left tray, increasing or decreasing the weight in the right tray and moving the code until the balance is measured;

E. Pour a proper amount of water into the measuring cylinder and read the liquid level indication at this time;

C tie the pendant with a thin thread and immerse it in the water of the measuring cylinder, then read the liquid level indicator.

(2) The mass of the pendant is m = 50g+20g+1.2g = 71.2g. 。

(3) the volume of the pendant V=8cm 3,

The density of the pendant is:

So the answer is: (1)E, c; (2)7 1.2; (3)8.9× 10 3 .
