Density = mass/volume (D=m/v), explain the difference in density of pure & salt water in words and using a mathematically based example
Why densities of pure and salt water are different
Click For Summary
SUMMARY
The discussion centers on the differences in density between pure water and salt water, emphasizing the formula for density (D = m/v). When salt is added to water, the mass increases due to the dissolved ions, while the volume changes as the ions fill the spaces between water molecules. The density of seawater ranges from 1020 to 1030 kg/m³, with total dissolved salts averaging 34.4 g/L. The presence of salt ions alters the arrangement of water molecules, resulting in a higher density compared to pure water.
