Question

What is the full form of
A.M.U and what 'u' means in chemistry
(Mass and molecules)
​

Answer 1

$\huge \boxed{ \underline{ \underline{ \bf{Answer}}}}$


Full Form of A.M.U is $\bf{Atomic\: Mass\: Unit.}$ .


$\underline{\bf{De}{fination}} :$

⏭️ The quantity 1/12th mass of C - 12 isotope is known as atomic mass unit.

⏭️ Since, Mass of 1 atom of C - 12 = 1.9924 × ${10}^{-23}$

Therefore, 1/12 th pary of the mass of 1 atom = 1/12 × 1.9924 × ${10}^{-23}$.
= 1.67 × ${10}^{-24}$ g
= 1 amu.

⏭️ Nowadays, amu is replaced by 'u' which means $\bf{unified \: mass}$ .

Answer 2

$\mathfrak{\huge{\pink{Answer}}}$

✨FULL FORM OF AMU IS ATOMIC MASS UNIT.

✨The 'U' is the standard unit of mass that quantifies mass on an atomic scale or molecular scale.

✨It is numerically equal to 1g/mol.

✨It is replacing Amu.
