HW #2: Seawater Salinity and Constant Proportions
The salinity of seawater is the ratio of the total mass (in grams) of salt per 1 kg (1000 g) of
seawater, and is expressed in units of parts per thousand (ppt, or %) which is approximately
the same as practical salinity unit (psu). A 1 kg sample of seawater that has a salinity of 34 %
thus contains 34 g of salt.
1. The average salinity of the oceans is 35 %. The total mass of the oceans is about 1.4 x 10²1
kg. If the oceans completely evaporated, how much salt (kg) would be left behind? Show all of
your work and box your answer (use extra paper if needed):
