sorry if that was confusing
To determine the mass of a mole of sodium carbonate (Na2CO3), you need to add up the atomic masses of each element present in the compound. The atomic masses can be found on the periodic table of elements.
The formula for sodium carbonate (Na2CO3) tells us that there are two sodium atoms (Na), one carbon atom (C), and three oxygen atoms (O) in one molecule of sodium carbonate.
The atomic masses for sodium (Na), carbon (C), and oxygen (O) are approximately 22.99 grams per mole, 12.01 grams per mole, and 16.00 grams per mole, respectively.
Calculating the mass of one mole of sodium carbonate:
2 Na atoms x 22.99 g/mol = 45.98 g
1 C atom x 12.01 g/mol = 12.01 g
3 O atoms x 16.00 g/mol = 48.00 g
Adding up the individual masses:
45.98 g + 12.01 g + 48.00 g = 105.99 g
Therefore, the mass of one mole of sodium carbonate is approximately 105.99 grams.
