C₃H₈ + 5O₂ = 3 CO₂ + 4 H₂O


44.1 g ----------- 4* 18.02 g

? g --------------- 75 g


mass of C₃H₈ = 75 * 44.1 / 4 * 18.02


mass of C₃H₈ = 3307.5 / 72.08


= 45.886 g of propane


number of moles:

45.886 / 44.1 = 1.0404 moles

1 mole --------- 22.4 L ( at STP )
1.0404 moles ----- ?

v = 1.0404 * 22.4 / 1

v = 23.304 L

hope this helps!
