The mass of sodium is 22,91.10e-23 g.
There are 2.54 grams of sodium in 1 gram of sodium carbonate.
Sodium carbonate does not exist as separate molecules as it forms an ionic lattice.
3 x 2 x 23 = 138g

Does not convert; milligrams (mg) and grams (g) are measures of weight or mass and mL (milliliters) is a measure of volume.
To determine the number of moles of sodium carbonate in 2 grams of hydrated sodium carbonate, we first need to calculate the molar mass of Na2CO3·xH2O. Once we have the molar mass, we can use the formula: Moles = Mass / Molar mass. Given that hydrated sodium carbonate has the molar mass of Na2CO3·xH2O, we can determine the number of moles in 2 grams of the compound.
By stoichiometry, 2 moles of sodium carbonate will produce 2 moles of sodium chloride. The molar mass of sodium chloride is approximately 58.44 g/mol, so 2 moles would weigh about 116.88 grams.
3 moles of sodium carbonate (Na2CO3) contain 6 moles of sodium ions (Na). Since the molar mass of sodium is about 23 g/mole, there would be approximately 138 grams of sodium in 3 moles of sodium carbonate.
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.
3 moles of sodium carbonate (Na2CO3) contain 6 moles of sodium ions (2 sodium ions per molecule of sodium carbonate). The molar mass of sodium is 23 g/mol, so 6 moles of sodium is approximately 138 grams in total.
The molar mass of sodium hydrogen carbonate is 84 grams per mole, therefore 0.5 moles of it weighs 42 grams.
