HOW TO SOLVE THIS PROBLEM?
The comments were interesting but I still do not know how to predict the
outcome of a simple experiment. Can somebody help? The mass of my floating
container is 62 grams, its height is 10.9 cm and its inner diameter is
8.5 cm. (A can from which Progresso Chicken Noodle soup was removed).

WHY IS THE TILT ANGLE EQUEL TO 50 DEGREES WHEN THE AMOUNT OF INNER WATER
IS 200 GRAMS? The angle is with respect to the vertical line. The wall
thickness was found to be 0.025cm.

The can asymmetry was negligible. This was verified by the fact that it had
no preferential side for tilting. (Always check for this, many containers
and cans are not exactly symmetric.) The tilt angle becomes 55 degrees
when amount of water inside is reduced to 170 grams. Crudely measured
angles can be off but by no more than 2 or 3 degrees.
