Correct option is C)
Remain unchanged.
This is because when you consider 1/6 in place of 1/12, since mass of carbon atom is still the same, new amu1 = 2amu ( where amu1 is new amu unit and amu is old amu unit)
So now
N
A
1 (avogadro’s number) becomes half ( N/2) since the weight of carbon corresponding to atomic weight becomes 6 gm in place of 12.( where N
A
1 is new avogardo’s number and N
A
is old avogardro’s number)
And we know that mass of one mole of substance is=N
A
×amu
So new atomic mass =N
A
1×amu 1=N
A
2×2 amu=N
A
×amu=old atomic weight.
