To find the number of moles of propene used, we need to use the molar mass of propene and the given mass.
Moles of propene = mass of propene / molar mass of propene
Moles of propene = 18.50g / 42.08 g/mol
Moles of propene = 0.4391 mol
Rounding to the correct number of significant figures gives us:
Moles of propene = 0.44 mol
Propane (C3H8, molar mass=44.09g/mol) can be prepared by the reaction of propene C3H6 molar mass=42.08 g/mol) with hydrogen (H2, molar mass=2.016 g/mol) according to the following balanced equation: C3H6+H2 C3H8
Assuming18.50g of propene and 28.50 of hydrogen are used, answer the following questions:
How many moles of propene are used? Be sure your answer has the correct number of significant figures.
