A) decrease to half
B) increase two fold
C) remain unchanged
D) be a function of the molecular mass of the substance.
Correct Answer: A
Solution :
[a]: 1 atomic mass unit on the scale of 1/6 of C-12 = 2 amu on the scale of 1/12 ofC-12. Now, atomic mass of an element \[\text{=}\frac{\text{Mass of one atom of the element}}{\text{1 amu(Here on the scale of }\frac{\text{1}}{\text{6}}\text{of}\,\text{C-12)}}\] \[\text{=}\frac{\text{Mass of one atom of the element}}{\text{2 amu(Here on the scale of }\frac{1}{12}\text{of}\,\text{C-12)}}\] \[\therefore \]Numerically the mass of a substance will become half of the normal scale.
