Question

hey hii guys i haven a dought can you plz help me

ok here is the question and I will be say half of the question after that I don't know what to do ...

express unified atomic mass unit in kg ?

here is the solution .....

1U = 1/12 mass of carbon
1U = 1/12 (12× 10 power of -3 / angadro number )
= 1/12 ( 12×10 power of -3 /6.023×10 power of 23 )
= 1/6.023× 10powerof -3×10 power of -23
=1/6.023×10 power of -26

now guys I don't know what to do next I'm totally confused .....

can you say me what next and also solution for that .....

Answer 1

Hey dear answer -

Here is your favorite answer

A mole is a very large number of atoms or molecules. This large number, known as Avogadro's number, is 6.02 x 1023. This number has been determined through a series of experiments conducted over a period of about 100 years by various researchers. A mole is to the macroscopic world what an individual particle is to the microscopic world with one difference: You can break a mole into fractions, but you can't do that to a particle such as an atom or molecule without changing it into something else.

Dear Student ,
1 unified atomic mass unit=1⋅6605×10−27 kg
