Theoretical yield
2.05 g salicylic acid x (180g aspirin/1 mol) x (1 mol/138 g salicylic acid)

The question is incomplete; part of the data required in the question are shown:

Theoretical Yield: 2.05 g salicylic acid x (180g aspirin/1 mol) x (1 mol/138 g salicylic acid) 2. Mass of filter paper 2.56 g 3. Mass of filter paper and aspirin 5.42 g 4. Mass of aspirin (3-2) g. Percent Yield [(4)/(1)] x 100

107%

Explanation:

We can calculate the theoretical yield as shown;

2.05g salicylic acid × 180g aspirin/1mol × 1 mol/138g of salicylic acid

Theoretical yield= 2.67 g of aspirin

Actual yield of aspirin is obtained from the experimental data;

Mass aspirin + filter paper= 5.42 g

Mass of filter paper= 2.56 g

Mass of aspirin= 5.42 g -2.56 g = 2.86 g

Hence actual yield of aspirin = 2.86 g

Percentage yield = actual yield/theoretical yield × 100

Percentage yield = 2.86/2.67 ×100 = 107%

a. they are both space stations

happy to

pls mark as brainliest.

cytokinesis is the splitting of a cell membrane to form 2 identical daughter cells. it's similar to mitosis as both cells have identical copies of dna and cytokinesis is a step in the mitotic cycle.
