1. 18g glucose is dissolved in 180g of water. The relative lowering of vapour pressure is a) 1 b) 1.8 c) 0.01 d) 0.001 ... Answer is c) Explanation: show Answer 2. 100g of a 10% (w/w) NaOH contains 10g of NaOH in. a) 100g of H 2 O b) 110g of H 2 O c) 10g of H 2 O d) 100g solution ... Answer is d) Explanation: First we need to calculate the mass of solute and solvent from 10%(W/W) NaOH. 10% (W/W) NaOH contains 10 gram (w) of NaOH(solute) dissolved in 100g (w) of solution. So, mass of solute = 10g Mass of solution = 100g show Answer 3. Which of the following W/W solutions has the lowest freezing point? a) 18% glucose b) 6% urea c) 34.2% sucrose d) 9% glucose ... Answer is c) Explanation: Depression in freezing point is colligative property and it is directly related to molality of solute. Solution with highest molality will show highest freezing point depressi...
