If we consider that  (in place of ) mass of carbon atom is taken to be the relative atomic mass unit, the mass of one mole of a substance will:

Strategy:
 Atomic mass is a relative comparison to a chosen standard (). While unit sizes change, the physical quantity (actual mass) of matter in one mole of an element is invariant.

Step 1: Evaluate the change in standard
If the standard unit () is redefined to be  instead of  of a Carbon atom, the unit itself doubles in value. Consequently, the numerical value of atomic mass would be halved.

Step 2: Determine impact on molar mass in grams
However, the "mole" is also defined relative to the
