For this problem, the solution is exhibiting some colligative properties since the solute in the solution interferes with some of the properties of the solvent. We use equation for the boiling point elevation for this problem. We do as follows: <span>
ΔT(boiling point) = (Kb)mi </span>ΔT(boiling point) = (0.512)(1.3/2.0)(2) ΔT(boiling point) = 0.67 degrees Celsius <span> T(boiling point) = 100 + 0.67 = 100.67 degrees Celsius</span>
The mass of aluminium foil is calculated as follows mass = density x volume density = 2.70 g/cm^3 volume 54 cm^3 mass of aluminium foil is therefore = 2.70 g/cm^3 x 54 cm^3 =145.8 grams cm^3 cancel out each other
