A [x] spins tablets in a circular motion. The tablets are then weighed to calculate the percent loss of weight from before being spun in said machine

It seems like you haven't provided a specific question to answer. However, based on the information you've given, I can explain the process you're describing.

1. Tablets are placed in a machine, which is not named but referred to as [x].

2. This machine spins the tablets in a circular motion. This could be for various reasons such as to coat the tablets, to test their durability, or to remove excess material.

3. After the tablets have been spun in the machine, they are weighed.

4. The weight of the tablets after being spun is compared to their weight before being spun.

5. The difference in weight is calculated to determine the percent loss of weight. This could be used to determine how much material was lost in the spinning process, or to test the quality and consistency of the tablets.

If you could provide more specific details or a specific question, I would be able to give a more precise answer.
