Homework Statement
a) Calculate the mass of F2 required to combine with N2 to produce 204 kg of NF3? b) what mass of N2 exactly combines with 25.91 mg of F2?
Homework Equations
Equation: N2 + 3F2 ---> 2NF3 Convert 204 kg to grams 204 kg X 1000 grams = 204,000 grams atomic mass of N = 14.0067 u atomic mass of F = 18.998403 u
The Attempt at a Solution
I am not sure where to start. What is known: 204 kg of NF3, what is unknown: mass of F2, mass of N2
From the equation, there are 3 moles of F2, 1 mole of N2, and 2 moles of NF3
I can multiply the atomic mass of F (((18.998403 times 3) + atomic mass of N = 14.0067)) = 56.995 + 14.007 to get 71.002 grams of NF3
