CaO + 2NH4Cl > 2NH3 + H2O + CaCl2

%yield = (actual yield/theoretical yield)*100 = ??

To calculate the percent yield, we need to compare the actual yield (16.3 g) to the theoretical yield (68.0 g) and express it as a percentage.

The percent yield formula is:

Percent Yield = (Actual Yield / Theoretical Yield) * 100

Substitute the given values into the formula:

Percent Yield = (16.3 g / 68.0 g) * 100

Calculate the value:

Percent Yield = 0.239705882 * 100

Percent Yield = 23.97%

Therefore, the percent yield is approximately 23.97%.

To find the percent yield, we need to compare the actual yield to the theoretical yield and calculate the percentage.

First, let's calculate the molar mass of NH3 (ammonia):
NH3: 1 atom of Nitrogen (N) + 3 atoms of Hydrogen (H) = (1 * 14.01 g/mol) + (3 * 1.01 g/mol) = 17.03 g/mol

Next, let's calculate the number of moles of NH3 based on the actual yield:
Actual yield of NH3 = 16.3 g
Number of moles of NH3 = Actual yield / Molar mass
Number of moles of NH3 = 16.3 g / 17.03 g/mol = 0.956 mol

Now, let's calculate the theoretical yield of NH3 based on the balanced chemical equation:
According to the balanced equation: 1 mol of CaO reacts with 2 mol of NH4Cl to produce 2 mol of NH3
So, the molar ratio between CaO and NH3 is 1:2.

The number of moles of CaO can be calculated as follows:
Mass of CaO = 112 g
Molar mass of CaO = 40.08 g/mol
Number of moles of CaO = Mass of CaO / Molar mass of CaO
Number of moles of CaO = 112 g / 40.08 g/mol = 2.794 mol

Using the molar ratio, the number of moles of NH3 that would be produced is:
Number of moles of NH3 = 2.794 mol of CaO * (2 mol of NH3 / 1 mol of CaO) = 5.588 mol

Now, let's calculate the theoretical yield of NH3:
Theoretical yield of NH3 = Number of moles of NH3 * Molar mass of NH3
Theoretical yield of NH3 = 5.588 mol * 17.03 g/mol = 95.08 g

Finally, we can calculate the percent yield:
Percent yield = (Actual yield / Theoretical yield) * 100
Percent yield = (16.3 g / 95.08 g) * 100 = 17.13 %

Therefore, the percent yield is approximately 17.13 %.
