Neco Model Questions Vol1 2018 Chemistry Question 29
Practice objective / multiple choice question 29 from the 2018 Neco Model Questions Vol1 Chemistry examination.
The normal boiling point of a solvent at 1 atm is \(78.0^{\circ}\text{C}\). Dissolving a non‑volatile solute raises the boiling point to \(80.5^{\circ}\text{C}\). The solvent's molal boiling‑point elevation constant is \(K_b = 0.512^{\circ}\text{C·kg mol}^{-1}\). Assuming the solute does not dissociate and is glucose (\(M = 180.16\ \text{g mol}^{-1}\)), calculate (a) the molality of the solution and (b) the mass of glucose required when \(250.0\ \text{g}\) of solvent is used.
