The molar mass of F₂ (F₁₂S₁₀) is calculated by adding the atomic masses of F (19.00 g/mol) and S (32.07 g/mol) for each atom present: 12(19.00) + 10(32.07) = 228.00 + 320.70 = 548.70 g/mol. Using the ideal gas law at STP (1 mole of any gas occupies 22.4 L), the volume occupied by 26.4 g of F₂ is found by first determining the number of moles: 26.4 g / 548.70 g/mol = 0.0481 mol. Then, multiplying the moles by the volume occupied by one mole at STP gives: 0.0481 mol * 22.4 L/mol = 1.077 L. However, given the options do not match this calculation, it seems there was a mistake in the calculation process. Correctly, for a typical gas at STP, 1 mole occupies 22.4 L, so the calculation should directly relate to finding the moles of the gas first and then applying this volume relationship correctly. The error in calculation suggests a misunderstanding in applying the molar volume at STP or in calculating the molar mass of the compound. Without the exact atomic masses or a clear formula, the precise calculation is challenging, but the principle remains that the volume at STP can be found through the molar volume concept.
