Propylene, C3H6, reacts with hydrogen under pressure to give propane, C3H8: C3H6(g) + H2(g) -----> C3H8(g) How many liters of hydrogen ( at 740 torr and 24 degree C) react with 18.0 g of propylene?
You would need
Start with the balanced chemical equation
Notice that you have a
Use propylene's molar mass to determine how many moles you have
Automatically, you have
Now use the ideal gas law equation to solve for the volume of hydrogen - don't forget to use Kelvin and atm
Rounded to two sig figs, the number of sig figs given for 24 degrees Celsius, the answer will be
