Question

If Avogadro number $N_A$ is changed from $6.022\times {10}^{23}mo{l}^{-1}$ to $6.022\times {10}^{20}mo{l}^{-1}$, this would change :

• A. the ratio of chemical species to each other in a balanced equation
• B. the ratio of elements to each other in a compound
• C. the definition of mass in units of grams
• D. the mass of one mole of carbon

Answer 1

Answer: (D)

the mass of one mole of carbon

If Avogadro number $N_A$ is changed from $6.022\times {10}^{23}mo{l}^{-1}$ to $6.022\times {10}^{20}mo{l}^{-1}$, this would change the mass of one mole of carbon from 12 g to 12 mg. However the following will remain unchanged.
(A) The ratio of chemical species to each other in a balanced equation
(B) The ratio of elements to each other in a compound
(C) The definition of mass in units of grams
