Final answer:
The mass of 1.00 mol of sodium hydrogen carbonate (NaHCO3) is 84.007 grams.
Step-by-step explanation:
The molar mass of sodium hydrogen carbonate (NaHCO3) can be calculated by summing the atomic masses of all the elements in the compound. The atomic masses of sodium (Na), hydrogen (H), carbon (C), and oxygen (O) are 22.99 g/mol, 1.008 g/mol, 12.01 g/mol, and 16.00 g/mol, respectively. Therefore, the molar mass of NaHCO3 is:
Na: 1 x 22.99 g/mol = 22.99 g/mol
H: 1 x 1.008 g/mol = 1.008 g/mol
C: 1 x 12.01 g/mol = 12.01 g/mol
O: 3 x 16.00 g/mol = 48.00 g/mol
Total: 22.99 g/mol + 1.008 g/mol + 12.01 g/mol + 48.00 g/mol = 84.007 g/mol
Therefore, the mass of 1.00 mol of NaHCO3 is 84.007 grams.
