Our bodies are about 0.85% salt, or about 0.85 grams salt in 100 ml. Because this is the normal level in our bodies, we call this concentration "normal saline solution".

When people sweat, they lose salt as well as water. So when we feed people intravenous solution for dehydration, we usually give them normal saline solution at this percent, not just water.

How many grams of salt would you add to a liter of water to make up normal saline solution?

Hint: How many cc or ml in a liter?

Hint: in water, grams, ml, and cc are all equal
