Answer:

67.0 L

Explanation:

Step 1: Given data

  • Moles of C₃H₈: 2.99 mol
  • Pressure: 1 atm (standard pressure)
  • Temperature: 273.15 K (standard temperature)

Step 2: Calculate the volume occupied by 2.99 moles of C₃H₈ at STP

C₃H₈ is a gas. If we assume ideal behavior, 1 mole of C₃H₈ at STP occupies 22.4 L.

2.99 mol × 22.4 L/1 mol = 67.0 L
