1
/
6
, in place of
1
/
12
, mass of carbon atom is taken to be the relative atomic mass unit, the mass of one mole of the substance will
be a function of the molecular mass of the substance
remain unchanged
increase two fold
decrease twice
Validate
Solution:
Let Relative Atomic Mass is in short R.A.M then
R.A.M
=
mass of
1
atom
1
12
×
mass of
1
atom of
C
12
⇒
mass of
1
atom
mass of
1
atom of
C
12
×
12
Now if we take
1
/
6
instead of
1
/
12
at first then the equation will become
⇒
mass of
1
atom
mass of
1
atom of
C
12
×
6
as 6 is half of 12 then R.A.M will decrease twice.
