Express unified atomic mass unit in kg....

Express unified atomic mass unit in kg.

Text Solution

Verified by Experts

Unified atomic mass unit, i.e., ` 1 a.m.u. = 1.67xx10^(-27)kg`
Infact, by definiton, `1 a.m.u. = (1)/(12) xx` mass of atom of `C^(12)`
`=(1)/(12)xx(12g)/(6.023xx10^(23)) = 1.67x10^(-24)g= 1.67xx10^(-27)kg`
