Calculate the number of atoms of oxygen present in 88 g of CO2. What would be the mass (in gm) of CO having the same number of oxygen  atoms?

Answers (1)

best_answer

88 g CO_2=2 \text { moles } \rightarrow 4 \text { moles of } O \text { atoms }

O \text { atoms }=2.4088 \times 10^{24}

\text { Same } O \text { atoms in } CO=4 \text { moles } CO

\text { Mass of } CO=4 \times 28=112 g

Hence,

O \text { atoms }=2.4088 \times 10^{24}

\text { Mass of } CO=112 g
