Water Density and Volume Calculation
What is the density of water at 20°C?
a) 0.998 g/mL
b) 1.000 g/mL
c) 1.020 g/mL
d) 1.050 g/mL
Answer:
b) 1.000 g/mL
Density is a measure of mass per unit volume. In the case of water at 20°C, the density is 1.000 g/mL. This means that each milliliter of water at this temperature has a mass of 1.000 grams.
