If `1//6`, in place of `1//12`, mass of carbon atom is taken to be the relative atomic mass unit, the mass of one one of a substance will:

A

decrease twice

B

increase two fold

C

remain unchanged

D

be a fraction of molecular mass of the substance.

Text Solution

Verified by Experts

The correct Answer is:
A
If atomic mass unit on the scale of `1/6` of C-12 is 2 a.m.u. on the scale of `1/12` of C-12, the mass of one mole of substance will become half of the normal value.
