Propane reacts with 3.15moles of oxygen how much propane reacts with oxygen
1 answer:
27.7g
Explanation:
Given parameters:
Number of moles of oxygen = 3.15moles
Unknown:
Mass of reacting propane = ?
Solution:
Equation of the reaction:
C₃H₈ + 5O₂ → 3CO₂ + 4H₂O
We work from the known to the unknown parameters.
The known in this expression is the number of moles of oxygen.
In the reaction:
5 moles of oxygen gas reacts with 1 mole of propane
3.15 mole of oxgen gas will react with = 0.63moles
Number of moles of reacting propane gas is 0.63moles
To find the mass;
mass = number of moles x molar mass = 0.63 x molar mass
molar mass of propane = (3 x 12) + (8x1) = 44g/mol
mass of propane = 0.63 x 44 = 27.7g
