How many moles of CO2 will be produced from 97g of C3H8 assuming O2 is available in excess

6.6 moles

Explanation:

Given dа ta:

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.
