Viraf J Dalal Chemistry Class 10 Textbook Solutions 2021 -

Key Topics: Arrhenius and Bronsted-Lowry concepts, pH scale, types of salts (normal, acid, basic, double, complex), preparation of salts (direct combination, displacement, neutralization, double decomposition).

Typical Solutions Include:

Let’s test a typical question from the 2021 edition of Chapter 5: Mole Concept.

Question: Calculate the number of molecules in 11.2 liters of CO2 gas at STP.

As per the Viraf J Dalal 2021 Solution:

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.

Step 2: Find moles of CO2.
( \textMoles = \frac\textGiven Volume\textMolar Volume = \frac11.222.4 = 0.5 \text moles)

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) viraf j dalal chemistry class 10 textbook solutions 2021

Final Answer: (3.011 \times 10^23) molecules of CO2.

(This level of clarity is what you get throughout the 2021 solutions.)
