Baking soda consists mostly of a single chemical. Look up what it is, its molecular weight and density, and determine the number of moles used in this recipe. Give your answer in moles but do not include the units.
Look up sodium hydrogen carbonate (or sodium bicarbonate). If you can get a Wikipedia site choose that and you can get the other information there. There is no way to get the mols for the recipe since you didn't give the recipe.
the volume for this question is 1 tsp. still not sure how to solve it.
To find the chemical composition of baking soda and its molecular weight, you can use an online database or search engine. Let's start by searching for the chemical name of baking soda.
A quick search reveals that the chemical name for baking soda is sodium bicarbonate (NaHCO3). To determine its atomic weight, we need to find the atomic masses of sodium (Na), hydrogen (H), carbon (C), and oxygen (O) and add them up based on the molecular formula.
Atomic masses:
- Sodium (Na) ≈ 22.99 g/mol
- Hydrogen (H) ≈ 1.01 g/mol
- Carbon (C) ≈ 12.01 g/mol
- Oxygen (O) ≈ 16.00 g/mol
Now let's calculate the molecular weight of sodium bicarbonate (NaHCO3):
Na: 1 atom × 22.99 g/mol = 22.99 g/mol
H: 1 atom × 1.01 g/mol = 1.01 g/mol
C: 1 atom × 12.01 g/mol = 12.01 g/mol
O: 3 atoms × 16.00 g/mol = 48.00 g/mol
Adding up the individual atomic masses:
22.99 g/mol + 1.01 g/mol + 12.01 g/mol + 48.00 g/mol = 84.01 g/mol
Therefore, the molecular weight (molar mass) of sodium bicarbonate is approximately 84.01 g/mol.
Next, to determine the number of moles used in a recipe, we need the mass of baking soda mentioned in the recipe. Since you haven't provided this information, I am unable to calculate the number of moles accurately.
However, to calculate moles from mass, you divide the mass of the substance by its molar mass. The formula is:
Number of moles = Mass (in grams) / Molar mass (in grams per mole)
Once you have the mass of baking soda, you can plug it into this formula along with the molar mass to calculate the number of moles used in the recipe.
