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

1 answer

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.
