Answer:
N = 5.8 × 10²⁴ molecules
Step-by-step explanation:
Step 1: Given and required data
- Moles of C₂H₄ (n): 9.6 mol
- Avogadro's number (NA): 6.02 × 10²³ molecules/mol
Step 2: Calculate the number of molecules (N) in 9.6 moles of C₂H₄
To convert moles to molecules we need Avogadro's number: there are 6.02 × 10²³ molecules of C₂H₄ per mole of C₂H₄
N = n × NA
N = 9.6 mol × 6.02 × 10²³ molecules/mol
N = 5.8 × 10²⁴ molecules
