Answer: The Correct answer is D.) Heat of combustion
Explanation:
I believe the correct answer from the choices listed above is the third option. The noble-gas notation for lead (Pb) would be [Xe]6s^2 4f^14 5d^10 6p^2. The standard electron configuration of lead is 1<span>s^2 </span>2s^2 2p^6 3s^2 3p^6 4s^2 3d^10 4p^6 5s^2 4d^10 5p^6 6s^2 4f^<span>14 5</span>d^10 6p^2 simplifying will lead to the part having the same configuration as xenon to be written as [Xe].
Molar mass of aspirin =180. So, moles of aspirin = 500 × 1 0 − 3 / 180 = 2.78 × 1 0 − 3 = 278 × 1 0 −
