\( 0.06 \%(\mathrm{w} / \mathrm{v}) \) aqueous solution of urea is isotonic with
- A \( 0.06 \% \) glucose solutio
- B \( 0.6 \% \) glucose solution
- C \( 0.01 \mathrm{M} \) glucose solution
- D \( 0.1 \mathrm{M} \) glucose solution
Answer & Solution
Correct Answer
(C) \( 0.01 \mathrm{M} \) glucose solution
Step-by-step Solution
Detailed explanation
Molarity of \( 0.06 \%\left(\frac{w}{v}\right) \) aqueous solution of urea
\[
\begin{array}{l}
=\frac{0.06 \times 1000}{60 \times 100} \\
=0.01 M
\end{array}
\]
As osmotic pressure \( (\Pi)= \) CRT
Therefore, \( 0.01 \mathrm{M} \) solution of urea will be isotonic with \( 0.01 \mathrm{M} \) glucose solution
\[
\begin{array}{l}
=\frac{0.06 \times 1000}{60 \times 100} \\
=0.01 M
\end{array}
\]
As osmotic pressure \( (\Pi)= \) CRT
Therefore, \( 0.01 \mathrm{M} \) solution of urea will be isotonic with \( 0.01 \mathrm{M} \) glucose solution
