the balanced chemical equation that shows the reaction between two gases:  nh3 and f2 is expressed as 8F2 + 2NH3 = N2F4 + 6HF2 . in this case, we are given with 66.6 grams of nh3 which is equal to 3.92 moles. using stoichiometry, 8 moles of F2 is needed to react with 2 moles of NH3. the final answer is equal to 595.48 grams of f2.

Answer:

The correct answer is 186.1gF2

Explanation:

Hello!

Let's solve this!

The reaction is:

2NH3 + 5F2 ---> N2F4 + 6HF

We have as data:

NH3 mass = 34g / mol

mass F2 = 95g / mol

mass NH3 = 66.6g

We don't use moles because we need mass in grams.

We calculate:

mass F2 = 66.6g * (95g / mol / 34g / mol) = 186.1gF2

The correct answer is 186.1gF2
