thanks ....is it like...

25g 50ml float 0.5
65g 40ml float 1.625
36g 35ml float 1.0285

and ya 1 more question

what is the difference between mass and weight?

Answered below. You need not repost question and answer. Just respond to the original.

Mass is a measure of how much matter an object has. Weight is a measure of how strongly gravity pulls on that matter. The mass of a stone would be the same irrespective of where you measured it, be it on Earth, the Moon or in deep space. The weight on the other hand is different in each of those three locations.

i just compared saw like whether it is 3.98

3.98 is the temperature of the water. Look up the density at 3.98 degrees C and compare THAT number with the density of each object. The density of water is about approximately 1.00 at the temperature but look it up to get the exact number.

Based on the information provided, it seems like you have a set of data with different mass and volume values, along with their corresponding floating values. However, it is not clear what these floating values represent or what you would like to know about them. If you could provide some additional context or specify what exactly you would like to know, I can help you further.

Regarding your second question, let's discuss the difference between mass and weight.

Mass is a measure of the amount of matter an object contains, and it remains the same no matter where the object is located. Mass is usually measured using units like grams or kilograms. It is an intrinsic property of an object and is independent of gravity.

Weight, on the other hand, is the force with which an object is attracted towards the center of the Earth (or any other celestial body with a gravitational field). Weight depends on both mass and the acceleration due to gravity. The unit of measurement for weight is the Newton (N) or pound (lb).

In simple terms, mass tells you how much matter an object has, while weight tells you the force exerted on that object due to gravity. While mass remains constant, weight can vary depending on the strength of the gravitational field acting on an object.
