Sulfur and fluorine react in a combination reaction to produce sulfur hexafluoride:
S (s) + 3F2 (g) SF6 (g)

What is the minimun number of moles of fluorine gas needed to completely react with 16 g sulfur?

a. 1
b. 1.5
c. 2
d. 3
e. 6

    You didn't type in the arrow? How do we know the difference between the products and the reactants?
    a. Convert 16 g S to moles. moles = grams/molar mass.
    b. Using the coefficients in the balanced equation, convert moles S to moles fluorine.
    Post your work if you get stuck.
