5short Q&A pairs drawn directly from our worked dot-point answer. For full context and worked exam questions, read the parent dot-point page.
What is concentration of solutions?Show answer
$c = n/V$ where $V$ is volume in litres. Units: mol L$^{-1}$ (M).
What is skipping the balanced equation?Show answer
Mole ratios require balanced coefficients.
What is forgetting limiting reagent?Show answer
Excess reactant does not determine product amount.
What is mixing mass and moles?Show answer
Convert to moles for stoichiometric reasoning; convert back to mass for final answer.
What is wrong molar mass?Show answer
Always include all atoms; check water vs methane vs ammonia carefully.
