By definition, a mole of any substamce contains 6.022142 x 1023 molecules. This constant, known as the Avogrado constant, is how we convert atomic weight to grams. If you know the atomic weight of, say, oxygen is 15.9994, then one mole of oxygen weighs 15.9994 grams. Anyway, one mole of NaHCO contains 6.022142 x 1023 molecules, but each molecule contains four atoms (one each of Sodium, Hydrogen, Carbon, and Oxygen). So the total number of atoms in a mole of NaHCO is 4 x 6.022142 x 1023 = 2.408857 x 1024.

How many moles of NaHCO3 are present in 3.00 g sample?
To find the moles of NaHCO3 in a 3.00 g sample, first calculate the molar mass of NaHCO3 (84.01 g/mol). Then, divide the mass of the sample by the molar mass to obtain the moles of NaHCO3. For this sample, 3.00 g / 84.01 g/mol ≈ 0.036 moles of NaHCO3 are present.

How many moles of NaCl would form from 3.25 moles of NaHCO3?
To find the moles of NaCl formed from NaHCO3, we need to consider the stoichiometry of the reaction. The balanced equation is: 2 NaHCO3 -> Na2CO3 + H2O + CO2 Therefore, for every 2 moles of NaHCO3, we get 1 mole of NaCl. Therefore, 3.25 moles of NaHCO3 would produce 1.625 moles of NaCl.
