Here are the solutions to the multiple-choice questions:

i) If the volume occupied by oxygen gas (O₂) at STP is $44.8 dm^3$ , the number of molecules of O₂ in the vessels are:

Step 1: Determine the number of moles of O₂. At STP, 1 mole of any gas occupies $22.4 dm^3$ . $Moles of O_2 = \frac{Given volume}{Molar volume at STP} = \frac{44.8 dm^3}{22.4 dm^3/mol} = 2 mol$ Step
