What is the density of water at room temperature in g/mL?

• A. 2.00 g/mL
• B. 0.78 g/mL
• C. 1.00 g/mL
• D. 0.50 g/mL

Answer: (C)

Verified step by step guidance

1. Recall that density is defined as mass divided by volume, expressed as \(\text{density} = \frac{\text{mass}}{\text{volume}}\).
2. Understand that the density of water at room temperature (around 25°C) is a well-known standard value used in chemistry and physics.
3. Remember that the commonly accepted density of pure water at room temperature is approximately 1.00 g/mL.
4. Compare the given options to this standard value to identify the correct density of water at room temperature.
5. Select the value closest to 1.00 g/mL, which is the accepted density of water at room temperature.
