Question

which pathway correctly describes how to solve the problem? \what is the mass of 1 molecule of c₅h₁₂ (pentane)?\ particles c₅h₁₂ → mol c₅h₁₂ → mass c₅h₁₂ mol c₅h₁₂ → particles c₅h₁₂ → mass c₅h₁₂ mass c₅h₁₂ → mol c₅h₁₂ → particles c₅h₁₂

Explanation:

To find the mass of 1 molecule of \( C_5H_{12} \), we first convert particles (molecules) to moles using Avogadro's number (\( 6.022 \times 10^{23} \) particles/mol). Then, we convert moles to mass using the molar mass of \( C_5H_{12} \). So the correct pathway is particles \( C_5H_{12}
ightarrow \) mol \( C_5H_{12}
ightarrow \) mass \( C_5H_{12} \).

Answer:

A. particles \( \ce{C5H12}
ightarrow \) mol \( \ce{C5H12}
ightarrow \) mass \( \ce{C5H12} \)
