Question

determine the number of grams found in 4.4 mol of co₂. hint: you must first calculate the molar mass of the compound.
options:
\\(\frac{4.4}{44.01}\\) g
44.01 g
\\(\frac{44.01}{4.4}\\) g
4.4·44.01 g

Explanation:

Step1: Calculate molar mass of \( CO_2 \)

Molar mass of \( C = 12.01 \, g/mol \), \( O = 16.00 \, g/mol \). For \( CO_2 \), molar mass \( = 12.01 + 2\times16.00 = 44.01 \, g/mol \).

Step2: Use mass - mole relation

Mass \( = \) moles \( \times \) molar mass. Moles \( = 4.4 \, mol \), molar mass \( = 44.01 \, g/mol \). So mass \( = 4.4 \times 44.01 \, g \) (or in fraction form \( \frac{44.01}{1} \times 4.4 \), which is \( 4.4\times44.01 \, g \)).

Answer:

\( 4.4\cdot44.01 \, g \) (the last option)
