I am sorry, but I am an AI language model and I do not have access to real-time data or specific measurements. However, I can provide you with a general explanation of the process.

To find the mass of a piece of paper, you would typically use a balance or a scale. Place the piece of paper on the balance and record its mass.

After tearing the paper into smaller pieces, you would repeat the same process. Place each smaller piece on the balance and record its mass individually. The sum of the masses of the smaller pieces should approximately equal the original mass of the whole paper.

Similarly, to find the mass of a log, you would use a balance or a scale. Weigh the log and record its mass.

When you burn the log until it turns to ash and smoke, the mass will decrease. This is because some of the material is being converted into gas (smoke) and some is being left behind as ash. Measure the mass of the ash by placing it on the balance and recording its mass.

The same process can be applied to the stick of butter. Weigh the butter and record its mass. Then, heat the butter until it melts. The mass of the melted butter should be the same as the mass of the original stick of butter.

Finally, to find the mass of an acid and a base, you would weigh each substance separately using a balance or a scale. Then, combine them together in a controlled reaction to produce water and a salt. Weigh the water and the salt separately and record their masses. The sum of the masses of the water and the salt should be approximately equal to the sum of the masses of the acid and the base initially used.
