Dimensional formula of atomic mass unit wavelength average atomic mass unit.

Answer 1

Answer:

Dimensional formulas :

atomic mass unit ⏩ [ M¹ L⁰ T⁰ mol⁻¹ ]

wavelength ⏩ [ M⁰ L¹ T⁰ ]

average atomic mass unit ⏩ [ M¹ L⁰ T⁰ mol⁻¹ ]

Explanation:

The seven standards of SI ( Standard International ) units are  as follows :

⏩ Mass

⏩ Length

⏩ Time

⏩ Electric Current

⏩ Temperature

⏩ Luminous Intensity

⏩ Amount of Substance

Dimensional formulas indicate the use of the above mentioned fundamental units or the S.I units .

The atomic mass unit has the unit of grams/moles and hence the power of moles is to the power - 1 . The power of mass is + 1 .

The unit of wavelength is in metres because it measures distance .

Average atomic mass unit has the same units as that of atomic mass unit .
