A solution containing `0.2563 g` of naphthalene (molecular mass = 128) in `50 g` of carbon tetrachloride yields a boling point elevation of `0.201^(@)C` while a solution of `0.6216 g` of an unknown solute in the same mass of the solvent gives a boiiling point elevation of `0.647^(@)C`. Find the molecular mass of unknown solute.

Text Solution

AI Generated Solution

To find the molecular mass of the unknown solute, we will use the concept of boiling point elevation and the formula related to it. We will follow these steps: ### Step 1: Understand the Formula The boiling point elevation (\( \Delta T_b \)) is given by the formula: \[ \Delta T_b = K_b \cdot m \] where: ...
