Answer:
6.6 moles
Step-by-step explanation:
Given data:
Moles of CO₂ produced = ?
Mass of C₃H₈ react = 97 g
Solution:
Chemical equation:
C₃H₈ + 5O₂ → 3CO₂ + 4H₂O
Number of moles of C₃H₈:
Number of moles = mass/ molar mass
Number of moles = 97 g/ 44.1 g/mol
Number of moles = 2.2 mol
Now we will compare the moles of C₃H₈ with CO₂ from balance chemical equation.
C₃H₈ : CO₂
1 : 3
2.2 : 3 ×2.2=6.6
Thus from 97 g of C₃H₈ 6.6 moles of CO₂ are produced.
