What is the molar mass of butane if 5.19 × 10¹⁶ molecules of butane weigh 5.00 μg?

Question

Quizplus · Accepted Answer

To find the molar mass, first calculate the number of moles of butane using Avogadro's number (6.022 × 10^23 molecules/mol). Then, use the given mass to find the molar mass. Moles = (5.19 × 10^16 molecules) / (6.022 × 10^23 molecules/mol) = 8.62 × 10^-8 mol. Molar mass = (5.00 × 10^-6 g) / (8.62 × 10^-8 mol) = 58.0 g/mol.
