The mass of sodium is 22,91.10e-23 g.
75 g sodium chloride contain 29,75 g sodium.

Dividing by the molar mass of sodium carbonate, we deduce that there are 4.25 x 10-5 moles in 4.5 x 10-3 grams of sodium carbonate.
The molar mass of sodium hydrogen carbonate is 84 grams per mole, therefore 0.5 moles of it weighs 42 grams.
one mole sodium carbonate contains 23X2 sodium, for three moles it will be 23X2X3=138 gram;
3.121x10-5 Grams of Na2CO3
One liter of Benedict's solution contains 173 grams sodium citrate, 100 grams sodium carbonate, and 17.3 grams cupric sulfate pentahydrate.
