Estimate the salt-to-water mass ratio that would produce the necessary change in temperature (i.e., 22-25°C.) Use the mass of salt calculated in the previous question and the water-to-salt ratio to determine the volume of water needed.
Sea water salinity is expressed as a ratio of salt (in grams) to liter of water. In sea water there is typically close to 35 grams of dissolved salts in each liter. It is written as 35‰. The normal range of ocean salinity ranges between 33-37 grams per liter (33‰ - 37‰).
