`P` and `Q` are two element that form `P_(2) Q_(3)` and `PQ_(2)`. If 0.15 mole of `P_(2) Q_(3)` weighs and 0.15 mole of `PQ_(2)` weighs `9.3 g`, what are the atomic weights of `P` and `Q`?

Text Solution

AI Generated Solution

To find the atomic weights of elements `P` and `Q`, we will use the information provided about the two compounds `P2Q3` and `PQ2`. We will set up equations based on the molar masses and the weights given. ### Step-by-Step Solution: 1. **Define Variables:** Let the atomic weight of `P` be \( A \) and the atomic weight of `Q` be \( B \). 2. **Calculate Molar Mass of \( P2Q3 \):** ...
