Correct Answer: Option D
Explanation:
Sugar \(+\) solution \(=\) sugar solution
\(50 cm ^3\)t \(40^{\circ} C\) solubility \(=34.2 g\) in \(50 g\) water Solution contain \(34.2 g\)
\(342 q\)
No. of mole \(=34.2 g / mol\)
\(=0.1\) mole
Solubility in \(mol / dm =\underline{10.1}\)
\(=0.1 \times 20\) \(=2 mol / dm ^3\)
Sugar \(+\) solution \(=\) sugar solution
\(50 cm ^3\)t \(40^{\circ} C\) solubility \(=34.2 g\) in \(50 g\) water Solution contain \(34.2 g\)
\(342 q\)
No. of mole \(=34.2 g / mol\)
\(=0.1\) mole
