The concentration of a \(100 \mathrm{~mL}\) solution containing \(X \mathrm{~g}\) of \(\mathrm{Na}_2 \mathrm{CO}_3\) (molecular wt. \(=106\) ) is \(Y M\). The values of \(X\) and \(Y\) are respectively.
- A \(2.12,0.05\)
- B \(1.06,0.2\)
- C \(1.06,0.1\)
- D \(2.12,0.1\)
Answer & Solution
Correct Answer
(C) \(1.06,0.1\)
Step-by-step Solution
Detailed explanation
\(W=\frac{M m V}{1000}\) \[ \begin{aligned} M & =\frac{W \times 1000}{m \times V} \\ Y & =\frac{X \times 1000}{106 \times 100} \\ \therefore \quad 106 Y & =10 X \end{aligned} \] Among the given options, only the values in option (c) can satisfy the equation (i), hence the…
