QUESTION #37 Molarity and Temperature Dependency
'x' g of NaCl is added to water in a beaker with a lid. The temperature of the system is raised from 1°C to 25°C. Which out of the following plots, is best suited for the change in the molarity (M) of the solution with respect to temperature? [Consider the solubility of NaCl remains unchanged over the temperature range]

QUESTION #49 Elevation of Boiling Point and Molar Mass Determination
When 1~g each of compounds AB and AB₂ are dissolved in 15~g of water separately, they increased the boiling point of water by 2.7~K and 1.5~K respectively. The atomic mass of A (in amu) is × 10⁻¹ (Nearest integer) (Given : Molal boiling point elevation constant is 0.5~ K~kg~mol⁻¹)
