Part 1: Who is Jim Clark and Why His Calculations Matter
Jim Clark is a retired chemistry teacher from New Zealand and the UK, and the founder of Chemguide. His website is not a flashy, animated tutorial. Instead, it offers text-heavy, crystal-clear explanations of why a calculation works, not just how to do it.
When students search for "jim clark chemistry calculations pdf upd", they are looking for:
- A portable file (PDF) they can print or use offline.
- Updated content ("upd") reflecting recent exam board changes (AQA, Edexcel, OCR, CIE).
- Organization — all calculation types in one document.
The Reality: Jim Clark does not distribute a single master PDF. However, you can legally compile the most updated content from his site into your own PDF. This article acts as your roadmap.
5. Gas Volume Calculations (Ideal Gas Law & Molar Volume)
- At Standard Temperature and Pressure (STP, 0°C, 1 atm): 1 mole of gas = 22.4 L
- At room temperature and pressure (RTP, 20°C, 1 atm): 1 mole = 24 L (approx.)
- Ideal gas law: PV = nRT (R = 0.0821 L·atm/(mol·K))

8. Enthalpy Change (ΔH) Calculations
- Formula: q = mcΔT, then ΔH = – q / moles
- Sign Conventions: Exothermic = negative ΔH. Endothermic = positive.
- PDF Warning: Correct units (J vs kJ) – a major source of errors.
3. Limiting Reactant Calculations
- Identify which reactant runs out first.
- Worked example: 5 g H₂ reacts with 50 g O₂ to form H₂O. Which is limiting?
- Moles H₂ = 5/2 = 2.5 mol
- Moles O₂ = 50/32 = 1.5625 mol
- Balanced: 2H₂ + O₂ → 2H₂O → 2:1 ratio.
- For 2.5 mol H₂, need 1.25 mol O₂ (we have 1.5625 mol, so O₂ is in excess → H₂ limiting).
1. Moles and Molar Mass
- Formula: ( n = \fracmM )
(( n ) = moles, ( m ) = mass, ( M ) = molar mass in g/mol) - Key idea: 1 mole = ( 6.022 \times 10^23 ) particles.
- Typical problem: Calculate moles in 5.0 g of NaOH (( M = 40.0 \text g/mol )).
