How many molecules of carbon monoxide,CO,comprise 4.82 grams?

Question

Quizplus · Accepted Answer

To find the number of molecules in 4.82 grams of carbon monoxide (CO), we first calculate the number of moles using the molar mass of CO (12.01 g/mol for carbon + 16.00 g/mol for oxygen = 28.01 g/mol for CO). Then, we use Avogadro's number (6.022 × 10^23 molecules/mol) to find the number of molecules.$$ \text{Moles of CO} = \frac{4.82 \, \text{g}}{28.01 \, \text{g/mol}} \approx 0.172 \, \text{moles} $$$$ \text{Number of molecules} = 0.172 \, \text{moles} \times 6.022 \times 10^{23} \, \text{molecules/mol} \approx 1.04 \times 10^{23} $$Therefore, the correct answer is 1.04 × 10^23 molecules of CO.
