x=80 grams
Answer:
There are no units with electro negativity. Linus Pauling designed a scale of electro negativity that ranks elements with respect to each other. So, for example, fluorine is a 4.0 in comparison to 0.7 for francium.

Molar mass:
CH₄ = 12 + 1 x 4 = 16.0 g/mol
CO₂ = 12 + 16 x 2 = 44.0 g/mol
Balanced <span>equation :
</span>
<span>CH</span>₄<span> + 2 O</span>₂<span> = CO</span>₂<span> + 2 H</span>₂<span>O
</span>
16.0 g CH₄ --------------- 44.0 g CO₂
(mass of CH₄) ----------- 46.4 g CO₂
mass of CH₄ = 46.4 x 16.0 / 44.0
mass of CH₄ = 742.4 / 44.0
= 16.87 g CH₄
hope this helps!
