The fact that Salt water is more dense than fresh water. That is a semantic memory.

Explanation:

Semantic memory is a type of explicit memory (along with episodic memory). Semantic memory stores factual information. For instance, you know the concept of what a car is (semantic memory), but you have memories of the day you bought your first car, and all the feelings you had that day (episodic memory).
