Answer: exactly 82 protons
Explanation:
Since lead has 82 protons the number of neutrons in an atom of lead-204 is 204-82=122. Similarly, lead-206 has 124 neutrons, lead-207 has 125 neutrons and lead-208 has 126 neutrons.

The theoretical yield of aspirin is <u>1.23 g</u>
Aspirin is a common drug with many uses. It relieves pain and reduces the risk of serious problems such as heart attack and stroke. It comes in many forms, including:
It is important to remember that aspirin alone does not lower blood pressure. However, its ability to thin the blood may benefit some people with high blood pressure.
moles of salicylic acid = mass / molar mass
=> 0.9457 / 138.2 = <u>0.006843 mol</u>
Acetic anhydride is in excess. Thus salicylic acid is the limiting reactant.
Total moles of aspirin that can form = moles of salicylic acid = 0.006843
mass of aspirin = number of moles of aspirin x molar mass of aspirin
= 0.006843 mol x 180.16g/mol = 1.23g
Thus theoretical yield of aspirin = 1.23 g
