Hint: Tetrafluoromethane, otherwise called carbon tetrafluoride or \[R - 14\], is the most straightforward perfluorocarbon (\[C{F_4}\]). As its IUPAC name shows, tetrafluoromethane is the per fluorinated partner to the hydrocarbon methane. It can likewise be named a haloalkane or halomethane.

Complete step by step answer:
On the off chance that you take a gander at the condition, you will see that for each one mole of \[C\] that is responded, one mole of \[C{F_4}\]is delivered. Thus, \[1.46\]moles of \[C{F_4}\] are created (expecting that there is sufficient \[F2\]). A mole of \[C{F_4}\] has a mass of around \[88\] grams, so \[1.46\] moles is equivalent to \[128.48\] grams. Adjusted to critical figures, your answer will be \[128\] grams.
Let’s do it bit by bit:
First Change moles of carbon to moles of \[C{F_4}\]
\[n\left( {C{F_4}} \right) = 1.46{\text{ }}mol{\text{ }}C{\text{ }} \times {\text{ }}\left( {\dfrac{{1{\text{ }}mol{\text{ }}C{F_4}}}{{1{\text{ }}mol{\text{ }}C}}} \right){\text{ }} = {\text{ }}1.46{\text{ }}mol{\text{ }}C{F_4}\]
At that point convert moles of \[C{F_4}\]to grams of \[C{F_4}\] utilizing the molar mass
$M\left( {{\text{C}}{{\text{F}}_4}} \right) = \left( {1 \times 12 + 4 \times 19} \right)gmo{l^{ - 1}} = 88gmo{l^{ - 1}}$
$m\left( {{\text{C}}{{\text{F}}_4}} \right) = nM = 1.46mol \times 88gmo{l^{ - 1}} = 128g$

So, the required answer is \[\left[ {128g} \right]\]

Note: On account of the dissimilar \[carbon-fluorine\] bonds, and the high electronegativity of fluorine. The carbon in tetrafluoromethane has a critical positive halfway charge which reinforces and abbreviates the four carbon–fluorine bonds by giving extra ionic character. Carbon–fluorine bonds are the most grounded single bonds in natural science. Moreover, they fortify as more carbon–fluorine bonds are added to a similar carbon.
Tetrafluoromethane is a valuable refrigerant yet in addition to a powerful greenhouse gas. It has an extremely high bond strength because of the idea of the carbon–fluorine bond. Tetrafluoromethane is once in a while utilized as a low temperature refrigerant. It is utilized in gadgets microfabrication alone or in blend with oxygen as a plasma etchant for silicon, silicon dioxide, and silicon nitride. It additionally has utilized in neutron finders.
