Chemistry for the EmSAT Exam
EmSAT Achieve Chemistry is required for pharmacy, medicine, chemical engineering, and biology programmes in the UAE. The test covers atomic structure, bonding, stoichiometry, organic chemistry (functional groups, reactions), acid-base chemistry, and electrochemistry at secondary-to-first-year-university level.
Locale-specific study guides
Pass-rate data, regulatory context, and study tips for Chemistry all change by candidate locale. Pick your context:
Common failure modes
These are the patterns that cause most candidates to lose marks on this topic. Recognising them in advance is half the work.
- !Mole calculation errors: not correctly applying M = mass/molar mass
- !Organic chemistry: confusing similar-looking functional groups (ester vs carboxylic acid)
- !Electrochemistry: incorrect identification of oxidation vs reduction at each electrode
Study tips
- 1Master the stoichiometry calculation chain: grams → moles → mole ratio → moles of product → grams.
- 2Learn the five key organic functional groups with their reactions: alcohol, aldehyde, carboxylic acid, ester, amine.
- 3Review the electrochemical series (standard electrode potentials) for common metals.

How many moles are in 40g of sodium hydroxide (NaOH)? (Molar mass of NaOH = 40 g/mol)
- A0.5 mol
- B1 molCorrect
- C2 mol
- D40 mol
Why this answer?
Moles = mass / molar mass = 40g / 40g/mol = 1 mol. This is the fundamental mole calculation. NaOH has molar mass: Na (23) + O (16) + H (1) = 40 g/mol.
