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

Options

A. decrease twice
B. increase two fold
C. remain unchanged
D. be a function of the molecular mass of substance

Answer

C

Explanation

1 mole = No. of atoms in 12.0000 g of `C^(12) = 6.022xx10^(23)`
Mass of 1 mole of a substance = Actual mass of 1 atom (or molecule) of the substanc `xx6.022xx10^(23)`
As mass of 1 mole of substance does not depend upon the atomic mass unit scale, the mass of one mole of substance will not change
