Calculate protein 100g of dry fish if 100g of raw fish contain 60g of protein and 25g of water.?

To calculate the protein content in 100g of dry fish, we first need to determine the amount of protein in the raw fish that is lost during drying. Given that 100g of raw fish contains 60g of protein and 25g of water, the remaining mass consists of solids (60g protein + 15g other solids = 75g total solids). When the fish is dried, the water is removed, concentrating the protein. Assuming no protein is lost during the drying process, 100g of dry fish would contain approximately 80g of protein (since the remaining solids are concentrated).
