Step 1: Recall the molar volume concept. 1 mole of any gas at STP occupies 22.4 L and contains (6.022 \times 10^23) molecules.
However, remember the golden rule: Use them after sincere self-attempt. Combine the conceptual depth of Dalal’s 2021 edition with regular practice of previous years’ papers. viraf j dalal chemistry class 10 textbook solutions 2021
Step 3: Find number of molecules. ( \textNumber of molecules = \textMoles \times \textAvogadro's Number ) ( = 0.5 \times 6.022 \times 10^23 = 3.011 \times 10^23 \text molecules) Step 1: Recall the molar volume concept

For ICSE Class 10 students, the journey through the periodic table, chemical bonding, and analytical chemistry can be daunting. Among the sea of reference books, Viraf J. Dalal’s "New Simplified Chemistry" (Class 10) has stood the test of time as the gold standard. The 2021 edition, in particular, holds a special place as it bridges the pre-COVID syllabus adjustments with the core ICSE requirements.
Step 2: Find moles of CO2. ( \textMoles = \frac\textGiven Volume\textMolar Volume = \frac11.222.4 = 0.5 \text moles)
