How many moles of baking soda are contributed by the 1/3 tsp. baking soda in this recipe? Assume that the density of baking soda is 1 g/ml and the molecular weight of baking soda is 84g/mol. Give your answer in moles, but without entering the unit.

1/3 tsp * 4.93ml/tsp * 1g/ml * 1mol/84g = ___ mol

To find the number of moles of baking soda contributed by the 1/3 tsp, we need to follow these steps:

1. Convert the volume of 1/3 tsp to milliliters (ml) since the density of baking soda is given in grams per milliliter (g/ml).
2. Calculate the mass of baking soda using the density and volume.
3. Convert the mass of baking soda to moles using the molecular weight of baking soda.

Let's go through these steps one by one:

1. Conversion of 1/3 tsp to milliliters (ml):
- Since 1 teaspoon (tsp) is approximately equal to 4.92892 milliliters (ml), we can calculate the volume of 1/3 tsp as follows:
Volume (ml) = 1/3 * 4.92892 ml

2. Calculation of the mass of baking soda:
- The density of baking soda is given as 1 g/ml. Therefore, the mass of baking soda can be calculated by multiplying the volume (in ml) with the density (in g/ml):
Mass (g) = Volume (ml) * Density (g/ml)

3. Conversion of mass to moles:
- The molecular weight of baking soda is given as 84g/mol. To convert the mass of baking soda (in grams) to moles, divide the mass by the molecular weight:
Moles = Mass (g) / Molecular weight (g/mol)

Now let's substitute the given values into these equations and calculate the number of moles of baking soda contributed by the 1/3 tsp:

1. Converting 1/3 tsp to milliliters (ml):
Volume (ml) = 1/3 * 4.92892 ml = 1.642974 ml

2. Calculating the mass of baking soda:
Mass (g) = 1.642974 ml * 1 g/ml = 1.642974 g

3. Converting mass to moles:
Moles = 1.642974 g / 84 g/mol = 0.019556 mi.

Therefore, the number of moles of baking soda contributed by the 1/3 tsp is approximately 0.019556.

To determine the number of moles of baking soda, we'll use the given density and molecular weight.

1. We need to find the mass of baking soda in grams. Since the density is given as 1g/ml, we know that 1/3 tsp (teaspoon) is equal to approximately 1.6 ml.
Mass = volume × density
Mass = 1.6 ml × 1 g/ml
Mass = 1.6 g

2. Now, we'll convert the mass of baking soda to moles using its molecular weight.
Moles = Mass / Molecular weight
Moles = 1.6 g / 84 g/mol
Moles ≈ 0.019 moles

Therefore, the 1/3 tsp of baking soda in this recipe contributes approximately 0.019 moles of baking soda.
