Answer:

It sounds fine, but it may be a bit too long. It's difficult to shorten things like this, but getting more straight to the point would give it that "catchy" feel.

Propane reacts with 3.15moles of oxygen how much propane reacts with oxygen​
Inessa [10]

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    \frac{3.15}{5} = 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
