Mass = Pressure*Area
You cannot These are different concepts. you need a volume and density to calculate mass, surface area provides neither (a cube and a sphere with the same surface area have different volumes and, had they been made of the same material, would have different masses).
Accurate measurements of time become possible after accurate measurement of length and mass because time taken by a heavy body to move a certain distance is more,and time taken by a light body to move a certain distance is less.
You do not calculate a log!You can calculate the surface area or the volume or, if you know the species, the mass or even time for which it would burn in a hearth. But the log, itself, is not something you can calculate.You do not calculate a log!You can calculate the surface area or the volume or, if you know the species, the mass or even time for which it would burn in a hearth.

No. Mass is what things are made of. Area is a way to how much length and width is covered by one of an objects sides.
If you went to Mars, your mass would remain exactly the same. You would weigh considerably less. Mass is determined by a balance. Weight is determined by how hard you push down against gravity.
No, the mass of a planet is not directly related to its surface area. Surface area is determined by the size and shape of the planet, not just its mass. For example, Earth has a smaller mass than Jupiter, but a larger surface area due to its size and composition.
Mass and volume are not determined by density. Rather density is determined by mass and volume
No, calculating the mass of Saturn using Kepler's Third Law and the motion of a single ice particle in its rings would not be accurate. The mass of Saturn is determined based on the orbits of its moons or spacecraft sent to study the planet, not by the motion of individual particles in its rings.
There are several ways to do this; the most accurate, as far as I know, is in the case of double stars. In that case, from the orbit of one of the stars, the mass of the other one can be determined quite accurately.
The relative atomic mass is 83.798. So where did you get that it is not determined.
A pipette is quite accurate. So yes weighing the contents of one into a vessel to get the weight (mass) would be an accurate way of measuring density.
The escape velocity is determined by the gravity of the planet which in turn is determined by the mass and size of the planet
Equivalent mass is determined because acid-base reactions involve the transfer of protons, not just the complete molecules of the acid and base. Equivalent mass takes into account this stoichiometry and allows for accurate calculations of the amount of acid or base reacting in the titration. Molar mass, on the other hand, only considers the total mass of the entire molecule, which may not reflect the true amount of substance reacting in the titration.
mass / volume = density
The most accurate measurement for a pellet with a mass of 3.25 grams would be to weigh it using a digital scale that can measure to at least two decimal places. This way, you can get a precise measurement of the pellet's mass.
The force of buoyancy can only be determined knowing the volume (not area) of an object and the density of the fluid it is placed in. It's value is equal to the weight of the displaced fluid and is independent of the mass of the object.
