Which of the following is the valueof amu?

A

`1.57 xx 10^(-24)` kg

B

`1.66 xx 10^(-24) ` kg

C

`1.99 xx 10^(-23)` kg

D

`1.66 xx 10^(-27)` kg

Text Solution

Verified by Experts

The correct Answer is:
D
amu represents atomic mass unit. It is used in place of unified mass unit.
1 amu = 1 avogram = 1 aston = 1 dalton
1 amu ` = (1)/(12) xx ` mass = 1 aston = 1 dalton ` = (1)/(12) xx 1.9924 xx 10^(-23) g`
`= 1.66 xx 10^(-24) g = 1.66 xx 10^(-27) kg`
