What volume does 0.5 mol of any gas occupy at room temperature and pressure? (1 mol = 24 dm3)

Answer and explanation

Correct answer: C. 12 dm3

  1. Step 1: Volume = moles x 24 dm3. Step 2. 0.5 x 24 = 12 dm3. Answer: 12 dm3. Why not the others: 24 dm3: That is the volume of one mole. 48 dm3: That is the volume of two moles. 6 dm3: That is the volume of a quarter of a mole.
