Propane burns in air to form water vapor and another gas. What is the volume of the water vapor at 500°C and 1 atm?​
kakasveta [241]

Answer:

253.85 L

Explanation:

We'll begin by writing the balanced equation for the reaction. This is illustrated below:

C₃H₈ + 5O₂ —> 3CO₂ + 4H₂O

From the balanced equation above, 4 moles of water vapor were produced.

Finally, we shall determine the volume of the water vapor produced as follow:

Mole water vapor (n) = 4 moles

Pressure (P) = 1 atm

Temperature (T) = 500 °C = 500 °C + 273 = 773 K

Gas constant (R) = 0.821 atm.L/Kmol

Volume (V) =?

PV = nRT

1 × V = 4 ×0.0821 × 773

V = 253.85 L

Thus, the volume of water vapor obtained is 253.85 L
