Ijmb Model Questions Vol1 2020 Chemistry Question 4
Practice practical question 4 from the 2020 Ijmb Model Questions Vol1 Chemistry examination. This question covers Mole Concept, Colligative Properties, Molecular Formula Determination .
An unknown aromatic compound (X) is suspected to have the empirical formula C₆H₅. To determine its molecular formula, a freezing‑point‑depression experiment is carried out using benzene as the solvent (K_f = 5.12 °C kg mol⁻¹). 1.00 g of X is dissolved in 50.0 g of benzene. The freezing point of pure benzene is 5.5 °C, whereas the solution freezes at 4.84 °C. The density of benzene is 0.877 g cm⁻³. All measurements are made at 25 °C and atmospheric pressure.
