Answer: The correct answer is Option A.

Step-by-step explanation:

To calculate the number of moles, we use the formula given by the equation:


\text{Number of moles}=\frac{\text{Given mass}}{\text{Molar mass}}

Where,

Given mass of
CO_2 = 454 grams

Molar mass of
CO_2=[12+(2* 16)]=44g/mol

Putting values in above equation, we get:


\text{Moles of }CO_2=(454g)/(44g/mol)=10.31mol

Hence, the correct answer is Option A.
