Q. If avogadro number $N_A$, is changed from $6.022 \times 10^{23}$ $mol^{-1}$ to $6.022 \times 10^{20}$ $mol^{-1}$, 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
Explanation

[Solution] A mole would then contain $6.022 \times 10^{20}$ atoms, so 1 mol of carbon would weigh $12 \times 10^{-3}$ g instead of 12 g. Answer (4).
