Final answer:

The density of water at 22.4°C is slightly lower than at 4°C, where it reaches its maximum, but commonly approximated as 1.0 g/cm³ for practical purposes.

Step-by-step explanation:

The density of water varies with temperature and exhibits unique behavior as it is cooled down. At 0°C, water has a density of nearly 1000 kg/m³ (specifically, 999.84 kg/m³). As we slightly increase the temperature to 22.4°C, the density slightly decreases due to the thermal expansion of water. However, this expansion is very small, as demonstrated by the fact that water is most dense at approximately 4°C, where its density is only about 0.0075% greater than at 2°C and 0.012% greater than at 0°C.



Given that the density at 4°C is considered a maximum and a reference point is provided with the density of water at 25°C being 1.0 g/cm³, we can infer that the density at 22.4°C would be slightly higher than 1.0 g/cm³ but less than the maximal density at 4°C. Unfortunately, without the exact data or a density-temperature chart specifically for 22.4°C, providing an exact figure is difficult. However, for practical purposes, it is common to approximate the density of water in this temperature range as 1.0 g/cm³ or 1000 kg/m³ in the absence of precise data.
