Question

How many moles are present in \(44\, \text{g}\) of \(CO_2\)?
(Molar mass of \(CO_2 = 44\, \text{g/mol}\))

• A. 1 mol
• B. 2 mol
• C. 0.5 mol
• D. 4 mol

Hint:

Always remember: \( \text{Moles} = \frac{\text{Mass}}{\text{Molar Mass}} \). Keep units consistent when using this formula.

Answer 1

The Correct Option is A

Calculate the number of moles using the formula: Number of moles = Given mass / Molar mass. \[ \text{Number of moles} = \frac{\text{Given mass}}{\text{Molar mass}} \] Provided values: - Mass of \(CO_2 = 44\, \text{g}\) - Molar mass of \(CO_2 = 44\, \text{g/mol}\) Calculation: \[ \text{Moles} = \frac{44}{44} = 1 \, \text{mol} \] **Conclusion:** The number of moles in \(44\, \text{g}\) of \(CO_2\) is 1 mol. This corresponds to option (1).
