Question

How many grams of carbon tetrafluoride, `CF_4`, are produced from the complete reaction of 1.46 moles of carbon in the reaction `C+2F_2 -> CF_4`?

Answer 1

128g

Explanation:

`n("CF"_4)=n("C") = 1.46mol`
`M("CF"_4)=(1xx12+4xx19)gmol^-1 = 88gmol^-1`
`m("CF"_4)=nM = 1.46molxx88gmol^-1 = 128g` (3s.f)
