Which of the following is arranged in order of increasing weight?
(A) \( 0.625 \mathrm{~g} \) of \( \mathrm{Fe}0.0105 \) equivalent of \( \mathrm{H}_{2} \mathrm{C}_{2} \mathrm{O}_{4} \cdot 2 \mathrm{H}_{2} \mathrm{O}6.02 \times 10^{21} \) atoms of \( \mathrm{Zn}0.006 \mathrm{~g} \) atom of \( \mathrm{Ag} \)
(B) \( 0.625 \mathrm{~g} \) of \( \mathrm{Fe}6.02 \times 10^{21} \) atoms of \( \mathrm{Zn}0.006 \mathrm{~g} \) atom of \( \mathrm{Ag}0.0105 \) equivalent of \( \mathrm{H}_{2} \mathrm{C}_{2} \mathrm{O}_{4} \cdot 2 \mathrm{H}_{2} \mathrm{O} \)
(C) \( 0.0105 \) equivalent of \( \mathrm{H}_{2} \mathrm{C}_{2} \mathrm{O}_{4} \cdot 2 \mathrm{H}_{2} \mathrm{O}0.006 \mathrm{~g} \) atom of \( \mathrm{Ag}6.02 \times 10^{21} \) atom of \( \mathrm{Zn}0.625 \mathrm{~g} \) of \( \mathrm{Fe} \)
(D) \( 0.0105 \) equivalent of \( \mathrm{H}_{2} \mathrm{C}_{2} \mathrm{O}_{4} \cdot 2 \mathrm{H}_{2} \mathrm{O}0.625 \mathrm{~g} \) of \( \mathrm{Fe}0.006 \mathrm{~g} \) atom of \( \mathrm{Ag}6.02 \times 10^{21} \) atoms
