I'm not sure what you mean, but weighing by difference is when you:Take the weight of an empty container, fill the container with a substance.Take the weight of the container holding the substance.Subtract the empty container's mass from the mass of the container and the substance.You will then get the mass of the substance.The result is what is called the "Tare" weight. That is the weight of the contents ONLY .And that would not be the mass of the substance,,,it would be the weight. Mass is a determination of how much space is taken up by the substance.

The device used for comparing the mass of an object to a known mass is a double pan balance, or a balance scale. This is a type of weighing scale where you put weights on one pan and the substance you are weighing on the other.

1 kilogram, one gram would be about a piece of paper
A paper scale or grammage scale is used to measure the grammage (weight) of a piece of paper. It typically measures the mass of paper in grams per square meter (g/m²) by weighing a standardized area of the paper.
pour the sample on the weighing paper
Mass is determined by weighing, so the piece of equipment is a scale.
Mass of a substance is usually measured in standard unit called kilogram (kg) . Hence unit of mass of a piece of pad paper will be in kg.
The balance should read 11.25 g. The total mass displayed on the balance is the mass of the sample (11.00 g) plus the mass of the weighing paper (0.25 g) for a total of 11.25 g.

The mass of an empty petri dish may be recorded in order to conduct weighing by difference. After a substance is added to the dish, the weight of the added substance can be calculated by taking the difference between the combined mass and the mass of the empty dish. The tare function on a scale performs this calculation automatically. However, the tare can easily be reset, and thus it is necessary to write the mass down so that it will not be lost.
The mass of the dust formed on burning a piece of paper is likely to be less than the original mass of the paper. This is because burning paper results in a conversion of some of the paper's mass into gases and ash, which can float away. The remaining dust would likely be a small fraction of the original mass.
The peice of paper compares to the paper airplane because they both have the same mass. Whether a paper is flat,folded in half or is shaped into a fancy paper boat it will always have the same amount of mass.
-- Get a pure piece of it. The size of the piece doesn't matter. -- Measure the mass of the piece. -- Measure the volume of the piece. -- The density of the substance is mass of the piece/volume of the piece.
Mrs. Clark can determine the total number of pieces of paper by dividing the total mass of paper by the mass of one piece of paper. In this case, if a single piece of paper weighed 20 g and she cut it into quarters, each quarter would weigh 5 g. Therefore, she knows that there are four pieces of paper in total.
You can demonstrate that a piece of chalk has mass by weighing it on a scale. Place the chalk on the scale and observe the reading, which indicates the gravitational force acting on the chalk due to its mass. A non-zero reading confirms that the chalk has mass.
