To find the number of molecules, first calculate the number of moles of CO₂ in 20.0 g. The molar mass of CO₂ is approximately 44.01 g/mol. Thus, 20.0 g CO₂ is 20.0 g / 44.01 g/mol = 0.4545 mol. Using Avogadro's number (6.022×10²³ molecules/mol), the number of molecules is 0.4545 mol × 6.022×10²³ molecules/mol = 2.74×10²³ molecules.
