How many molecules of sucrose (C₁₂H₂₂O₁₁, molar mass = 342.30 g mol^-1) are contained in 14.3 mL of 0.140 mol L^-1 sucrose solution?

Question

Quizplus · Accepted Answer

To find the number of molecules, first calculate the moles of sucrose: 0.140 mol/L * 0.0143 L = 0.002002 mol. Then, multiply by Avogadro's number (6.022 × 10^23 molecules/mol) to get the number of molecules: 0.002002 mol * 6.022 × 10^23 molecules/mol = 1.21 × 10^21 molecules.
