What is the density of glycerol in g/cm^3 at room temperature?

• A. 0.78 g/cm^3
• B. 1.26 g/cm^3
• C. 0.92 g/cm^3
• D. 2.13 g/cm^3

Answer: (B)

Verified step by step guidance

1. Understand that density is defined as mass per unit volume, expressed as \(\text{density} = \frac{\text{mass}}{\text{volume}}\).
2. Recognize that the problem asks for the density of glycerol at room temperature, which is a known physical property and typically found in reference tables or reliable chemical data sources.
3. Recall or look up the standard density value of glycerol at room temperature (around 20-25°C), which is approximately 1.26 g/cm\(^{3}\).
4. Compare the given options with the known standard density value to identify the correct answer.
5. Confirm that the density of glycerol is significantly higher than water (1.00 g/cm\(^{3}\)) but less than some very dense liquids, making 1.26 g/cm\(^{3}\) the reasonable and correct choice.
