Understand that density is defined as mass per unit volume, typically expressed as \(\text{density} = \frac{\text{mass}}{\text{volume}}\).
Recall that the density of pure water at room temperature is approximately 62.4 lb/ft\(^3\).
Recognize that seawater contains dissolved salts, which increase its density slightly compared to pure water.
Estimate that the typical density of seawater is therefore a bit higher than 62.4 lb/ft\(^3\), often close to 64 lb/ft\(^3\).
Compare the given options to this known value to identify which is closest to the typical density of seawater.
