Question

find value of 1 atomic mass unit numerically​

Answer 1

Answer:

Explanation:

1 atomic mass unit is equal to 1/6.022*10^23. I can say so because according to mole concept 1 mole(6.022*10^23) of atoms of any pure substance is equal to its atomic mass in grams, if we take case of hydrogen( it's atomic mass unit is 1)

Mass of 1 hydrogen atom*6.022*10^23=1 gram

Therefore 6.022*10^23 atomic mass unit =1gram

So,1 atomic mass unit =1/6.022*10^22 gram

Answer 2

The value of 1 amu is 1.67377 x 10 -27 kilogram (kg), or 1.67377 x 10 -24 gram (g). 

The mass of an atom in AMU is roughly equal to the sum of the number of protons and neutrons in the nucleus.
