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 Lhope this helps!
The molar mass of magnesium is 24.305 g/mol
