What is the volume of 3 mol of any gas at room temperature and pressure? (Molar volume = 24 dm/mol at r.t.p.)
Answer and explanation
Correct answer: D. 72 dm
- Step 1: Volume dm/mol.
- Step 2: dm.
Answer
72 dm.
Why not the others: 0.125 dm: it divides moles by the molar volume. 8 dm: it divides the molar volume by the moles. 72000 dm: it converts to cm and keeps the dm unit.
