Question

Water is most dense at 4 degrees Celsius. Since at this temperature 1 ml of water has a mass of 1 g. What is its density?

Answer 1

The density is 1. 1/1=1

Answer 2

Answer: 1 g/cm³

Explanation:

The density of a substance is defined as the ratio of its mass to its volume.

At 4 °C, 1 mL water has 1 g mass.

1 mL = 1 cm³

Thus, ρ = m/V

m = 1 g

V = 1 cm³

⇒ ρ = m/V = 1 g/ 1 cm³

So, the density of water at 4° C is 1 g/cm³
