What is the molar mass of 1-butene if 5.38 × 10¹⁶ molecules of 1-butene weigh 5.00 μg?

Question

Quizplus · Accepted Answer

The molar mass is calculated by dividing the mass of the sample by the number of moles. Given the number of molecules (5.38 × 10^16) and the mass (5.00 μg), we first convert the number of molecules to moles using Avogadro's number (6.022 × 10^23 molecules/mol). Then, we convert the mass from micrograms to grams. The calculation leads to a molar mass close to 56.0 g/mol, matching option A.
