Assuming 18.50 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.

moles of propene

To find the moles of propene used, you need to divide the given mass of propene by its molar mass. The molar mass of propene is:

3(12.01 g/mol) + 6(1.01 g/mol) = 42.08 g/mol

Now, you can calculate the moles of propene:

(18.50 g) / (42.08 g/mol) = 0.44 mol

Therefore, 0.44 moles of propene are used.
