Question

How many moles are present in 454 grams of CO2?

A. 10.31 mol
B. 4.54 mol
C. 37.83 mol
D. 14.18 mol
E. 1.3 mol

Answer 1

A. 454 ÷ 44 =10.318181818182 = 10.31 Ans

Answer 2

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.
