Arrange the following solutions in increasing order of their concentration.
(A) \(7.5 \text{ g } KCl\) (74.5 g \(mol^{-1}\)) in 100 mL solution
(B) \(3 \text{ g } Urea\) (60 g \(mol^{-1}\)) in 1 L solution
(C) \(3.6 \text{ g } glucose\) (180 g \(mol^{-1}\)) in 100 mL solution
(D) \(4 \text{ g } NaOH\) (40 g \(mol^{-1}\)) in 1 L solution
Choose the correct answer from the options given below:
- A (A), (C), (D), (B)
- B (A), (B), (C), (D)
- C (B), (D), (C), (A).
- D (C), (B), (D), (A)
Answer & Solution
Correct Answer
(C) (B), (D), (C), (A).
Step-by-step Solution
Detailed explanation
\(M_A = \frac{7.5 \text{ g}}{74.5 \text{ g mol}^{-1}} \times \frac{1}{0.1 \text{ L}} = 1.0067 \text{ M}\) \(M_B = \frac{3 \text{ g}}{60 \text{ g mol}^{-1}} \times \frac{1}{1 \text{ L}} = 0.05 \text{ M}\)…
