If the molar mass of a substance is 34.1 g/mol, what is the mass of 3.01 x 10²⁴ molecules of the substance?

Question

Quizplus · Accepted Answer

To find the mass, first convert molecules to moles using Avogadro's number (6.022 x 10^23 molecules/mol). Then multiply the number of moles by the molar mass: (3.01 x 10^24 molecules) / (6.022 x 10^23 molecules/mol) = 5 moles. 5 moles x 34.1 g/mol = 170.5 g, which is approximately 1.70 x 10^2 g.
