In the presence of H2 and Pt, propene is reduced to propane. CH3CH=CH2 (propene) + H2 >> CH3CH2CH3 (propane)

79 moles of propene = 2.molar mass of propene = 42.moles of propene in 442g = 442 /42 =10.52 moles so moles of propane expected = 10.......
a. How many moles of H2 are required to completely react with 6.23 mol of propene?
b. How many moles of H2 are required to completely react with 2.79 mol of propene?
c. How many moles of propane are expected from the complete reaction of 420 g of propene?
d. How many moles of propane are expected from the complete reaction of 442 g of propene?

CH3CH=CH2 + H2 >> CH3CH2CH3 is balanced so

Moles of H2 that will react with 6.23 moles of propene = 6.23
moles of H2 that will react with 2.79 moles of propene = 2.79

molar mass of propene = 42.00 so moles in 420 g of propene = 420 / 42 = 10 moles
moles of propane expected = 10

moles of propene in 442g = 442 /42 = 10.52 moles so moles of propane expected = 10.52
