**Chemical Reaction Stoichiometry Problem**

**Problem 7B-1:**

Consider this chemical reaction:
\[ \text{P}_4(s) + 5 \text{O}_2(g) \rightarrow 2 \text{P}_2\text{O}_5(s) \]

How many grams of diphosphorus pentoxide are produced from 2.5 billion oxygen molecules?

---

**Explanation:**
This problem involves stoichiometry, where you will calculate the amount of a product (diphosphorus pentoxide, \(\text{P}_2\text{O}_5\)) formed from a given number of reactant molecules (oxygen, \(\text{O}_2\)). You will need to convert the number of \(\text{O}_2\) molecules to moles using Avogadro's number, apply the stoichiometric ratios from the balanced equation, and finally convert moles of product to grams using the molar mass of \(\text{P}_2\text{O}_5\).
