The average atomic mass of the imaginary element : 47.255 amu
<h3>Further explanation </h3>
The elements in nature have several types of isotopes
Isotopes are elements that have the same Atomic Number (Proton)
Atomic mass is the average atomic mass of all its isotopes
Mass atom X = mass isotope 1 . % + mass isotope 2.% ..
isotope E-47 47.011 amu, 87.34%
isotope E-48 48.008 amu, 6.895
isotope E-49 50.009 amu, 5.77%

The mass of CO2 that would be produced is 144.03 g
From the equation of the reaction, the mole ratio of C2H4 input to CO2 produced is 1:2.
Recall that: mole = mass/molar mass
mole of 45.9 g C2H4 = 45.9/28.05
= 1.6364 moles
Thus: equivalent moles of CO2 = 1.6364 x 2
= 3.2727 moles
Mass of 3.2727 moles of CO2 = moles x molar mass
= 3.2727 x 44.01
= 144.03 g
