Scientists have found that it's not possible to detemine their exact positions with any certainty.
no
Why scientist use SI unitsSo all scientists no matter what country their in can do the experiment and know how much of a specific material to use. It is because the length of each person varies.But SI units show exact length whenever it is taken.

We can use a conductivity meter (salinometer), a densimeter or for exact results analytical chemistry instruments for the determination of sodium.
scientists know the exact spot where an earthquake begins because they use a ritcher scale
Scientists must rely on estimates when they cannot obtain exact numbers.
Clocks have been around since ancient times. The origins are not exact but it is widely known that the sundial was the first instrument used to measure time. Using the exact point of midday the sundial morphed into the obelisk that the Egyptians used to pinpoint midday.
answer
No. Atomic masses have to be determined by using measuring instruments, which means that they can never be determined precisely. Every measuring instrument has a limit to its accuracy. There is wide agreement that it is impossible to build a perfect measuring instrument. Scientists have constructed some amazingly accurate measuring techniques, but no exact ones.
