Question

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 mass of one mole of a substance will

(a) decrease twice
(b) increase two fold
(c) remain unchanged
(d) be a function of the molecular mass of the substance.

Answer 1

(a) : 1 atomic mass unit on the scale of 1/6 of C-12 = 2amu on the scale of 1/12 of C-12.
Now, atomic mass of an element
