The density of the mixture is determined as 1,013.75 kg/m³.
The density of the mixture is calculated as follows;
density = total mass of the mixture / total volume of the mixture
mass of the fresh water = density x volume
= 1000 kg/m³ x 0.0018 m³
= 1.8 kg
mass of the sea water = 1025 kg/m³ x 0.0022 m³
= 2.255 kg
Total mass = 1.8 kg + 2.255 kg = 4.055 kg
Total volume = 0.0018 m³ + 0.0022 m³ = 0.004 m³
Density = 4.055 kg/0.004 m³ = 1,013.75 kg/m³
Thus, the density of the mixture is determined as 1,013.75 kg/m³.
