Question

Donna was studying the following reaction for a stoichiometry project: S(s) + 3 F2(g) → SF6(s) She wondered how much she could obtain if she used 3.5 g of fluorine. What mass of SF6(s) would she obtain from the calculation using this amount of fluorine?

Answer 1

Answer:
4.48 g of SF₆

Solution:

The reaction is as follow,

S + 3 F₂ → SF₆

According to equation,

113.94 g (3 mole) F₂ produced = 146.06 g (1 mole) SF₆
So,
3.5 g F₂ will produce = X g of SF₆

Solving for X,
X = (3.5 g × 146.06 g) ÷ 113.94 g

X = 4.48 g of SF₆
