Understanding the Initial Salt Dissolution: Why 500 L of Water with 30% Salt Equals 150 L of Salt Solution When preparing saltwater solutions, understanding the precise concentration and volume relationships is crucial—especially in applications like aquaculture, water treatment, or industrial processes. A common calculation involves determining the volume of salt dissolved in a given water volume. For example, mixing 500 liters of water with a 30% salt concentration yields 150 liters of actual salt solution. This article explains the science behind this transformation, the importance of accurate measurements, and real-world implications. ### What Does 30% Salt Concentration Mean? A 30% salt concentration means 30% of the total solution volume by volume is salt solution (sodium chloride dissolved in water), and 70% remains pure water. This differs from simply adding salt to water by weight or volume without clarifying what percentage of the final mixture is salt.
