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

Answer:
17.3 g Cr
Explanation:
To find the mass of chromium, you need to (1) convert moles Si to moles Cr (using the mole-to-mole ratio from equation coefficients) and then (2) convert moles Cr to grams Cr (using the atomic mass). It is important to arrange the conversions in a way that allows for the cancellation of units. The final answer should have 3 sig figs to match the sig figs of the given value (0.250).
3 Si + 2 Cr₂O₃ ---> 4 Cr + 3 SiO₂
^ ^
Atomic Mass (Cr): 51.996 g/mol
0.250 moles Si 4 moles Cr 51.996 g
------------------------- x -------------------- x ------------------- = 17.3 g Cr
3 moles Si 1 mole
