O-Level Chemistry Periodic Table (6092): Free PDF
The O-Level Chemistry paper prints a periodic table with the proton number, symbol, name and relative atomic mass of every element, rounded to whole numbers except chlorine at 35.5. Under the table it gives the molar volume of a gas, 24 dm³ at room temperature and pressure, and the Avogadro constant, 6.02 × 10²³ mol⁻¹.

Questions students ask
What relative atomic mass should I use for chlorine?
Use 35.5. It is the only element on the O-Level table given to one decimal place. Every other relative atomic mass is a whole number, so copper is 64 and magnesium is 24.
Is the periodic table given in every O-Level Chemistry paper?
Yes. The 6092 syllabus states that a copy of the Periodic Table of Elements is printed as part of the papers, so you do not need to memorise relative atomic masses.
What is the molar volume of a gas at r.t.p.?
24 dm³ per mole at room temperature and pressure. It is printed under the periodic table, so moles of gas = volume in dm³ ÷ 24.
