Key Concepts
Here are the essential concepts you must grasp in order to answer the question correctly.
Temperature Scales
Temperature can be measured using different scales, the most common being Celsius (°C) and Fahrenheit (°F). Each scale has its own zero point and degree increments, which means that a direct comparison between the two requires conversion formulas.

The pH Scale
Conversion Formula
To convert Fahrenheit to Celsius, the formula used is °C = (°F - 32) × 5/9. This formula accounts for the difference in the zero points and scaling between the two temperature systems, allowing for accurate conversion.

Textbook Question
(a) A sample of tetrachloroethylene, a liquid used in dry cleaning that is being phased out because of its potential to cause cancer, has a mass of 40.55 g and a volume of 25.0 mL at 25 °C. What is its density at this temperature? Will tetrachloroethylene float on water? (Materials that are less dense than water will float.)

(b) Carbon dioxide (CO2) is a gas at room temperature and pressure. However, carbon dioxide can be put under pressure to become a 'supercritical fluid' that is a much safer dry-cleaning agent than tetrachloroethylene. At a certain pressure, the density of supercritical CO2 is 0.469 g/cm3. What is the mass of a 25.0-mL sample of supercritical CO2 at this pressure?
