"Number of sulfur atoms"Number of sulfur atoms == 100xxN_A100×NA...where...

Explanation:

"Number of sulfur atoms"Number of sulfur atoms == 100xxN_A100×NA...where N_ANA == "Avogadro's number"Avogadro's number, 6.022xx10^23*mol^-16.022×1023mol1.

And thus "Number of sulfur atoms"Number of sulfur atoms == 100*molxxN_A100mol×NA == 10^2*molxx6.022xx10^23*mol^-1=6.022xx10^25102mol×6.022×1023mol1=6.022×1025 "sulfur atoms"sulfur atoms.

How many sulfur atoms in 100*mol100mol of Na_2^(+)S_2O_3^(2-)Na+2S2O23, "sodium thiosulfate"sodium thiosulfate?
