If the molar mass of a substance is 44.01 g/mol, what is the mass of 1.05 × 10²⁴ molecules of the substance?

Question

Quizplus · Accepted Answer

To find the mass of 1.05 × 10^24 molecules of a substance with a molar mass of 44.01 g/mol, first convert the number of molecules to moles using Avogadro's number (6.022 × 10^23 molecules/mol). 1.05 × 10^24 molecules / 6.022 × 10^23 molecules/mol = 1.74 moles. Then, multiply the number of moles by the molar mass: 1.74 moles × 44.01 g/mol = 76.7 g.
