Answer: The amount of carbon dioxide for a given amount are 0.28 moles.
Explanation:
To calculate the number of moles, we use the equation:
\(\text{Number of moles}=\frac{\text{Given mass}}{\text{Molar mass}}\)
We are given:
Given mass of carbon dioxide = 12.3 g
Molar mass of carbon dioxide = 44 g/mol
Putting values in above equation, we get:
\(\text{Moles of carbon dioxide}=\frac{12.3g}{44g/mol}=0.28mol\)
Hence, the amount of carbon dioxide for a given amount are 0.28 moles.
