Problem
The density of a certain sugar solution varies with temperature as shown in the table below:
Temperature (°C) : 15 | 25 | 35
Density (g cm−3) : 1.07 | 1.05 | 1.03
A laboratory flask is completely filled with 2.10 kg of this solution at 25 °C.
(i) Using the data, calculate the volume of the solution in litres when it is at 25 °C.
(ii) The flask is sealed so that its volume remains unchanged. The solution is then cooled to 15 °C. Determine the new mass of the solution required to fill the flask completely at this temperature.
(iii) Compute the difference in mass between the two temperatures and explain, with calculations, why this change occurs.
