SUMMARY
The total mass of sodium chloride in seawater can be calculated using the volume of seawater, its density, and the mass percentage of sodium chloride. Given a total volume of 1.5 x 1021 L and a sodium chloride concentration of 3.1% by mass, the mass of seawater is first determined using the density of 1.03 g/mL. The correct calculation yields approximately 61,324.93 kg of sodium chloride, which converts to about 67.5 tons.
PREREQUISITES
- Understanding of density and its units (g/mL, kg/L)
