A bottle read: “0.2 mol/dm³ HCl, 250 cm³.” How many moles?
To help point you toward the right formulas or specific practice problems, let me know:
Lesson: V(gas) = n × 24 dm³/mol

Mastering chemical calculations is the single biggest hurdle for most advanced chemistry students. Jim Clark’s Calculations in AS and A Level Chemistry is widely considered the gold standard textbook for overcoming this challenge.
Task: Volume of 0.5 mol CO₂? Volume = 0.5 × 24 =

Jim Clark's true gift to the chemistry community is the legendary website. Originally developed from his one-to-one teaching sessions at Truro School, it has become an indispensable free resource for students worldwide, receiving approximately 1.4 million visits per month globally and is likely used by almost every A-Level chemistry student in the UK.
