What is the formula weight of lead iodide (PbI₂)? A)334.1 B)168.7 C)295.6 D)461.0 E)668.2

Question

Quizplus · Accepted Answer

The formula weight of lead iodide (PbI2) is calculated by adding the atomic weights of lead (Pb) and iodine (I) for two atoms. The atomic weight of lead is approximately 207.2 u, and the atomic weight of iodine is approximately 126.9 u. Therefore, the formula weight of PbI2 is 207.2 u (for Pb) + 2 * 126.9 u (for I) = 461.0 u.
