Answer 1

Please mark as brainliest

Answer:

There's nothing to explain

The mass is taken average while studying to make easy study.

But in periodic table, the masses are not approximated upto 10th, 100th and 1000th places and sometimes much more after decimal placesm

For example, The atomic mass of hydrogen is given as 1.0079u actually(periodic table)

but, its approximately written only 1u
