According to the equation you have 1 mole of C2H4 and 3 moles of O2.
1 • (22.4L / 270L) = 3 • (22.4L / x)
1/270L = 3/x
x = 3(270) / 1
x = 810 L
810 Liters of oxygen will react with 270 liters of ethene (C2H4) at STP
Too high because there will be extra water weight on the silver chloride therefore making it seem like there is more silver than there actually is
1.8e-6 this should be the correct answer according to my mass converter.
