Answer: 35 grams of salt for every 1,000 grams of water
Step-by-step explanation:
Salinity is the content of salt dissolved in a body of water. It is generally defined as the total amount in grams of dissolved salt contained in a kilogram (or 1000 grams) of seawater, and this is called
:
![1 ppt=(1 g [disolved-salts])/(1000 g [seawater])](https://img.qammunity.org/2018/formulas/geography/high-school/wacggdbj73sf3y57zi40mq0gh2dilqcqhj.png)
So, if we have a salinity of
this is equivalent to 35 grams of disolved salts in 1000 grams of seawater:
![35 ppt=(35 g [disolved-salts])/(1000 g [seawater])](https://img.qammunity.org/2018/formulas/geography/high-school/4tr1zzst37ibzn0i0e0katdh0bvcy83eay.png)
This is in fact a dimensionless value, which was defined in 1902 in this way by the amount of sodium chloride present in water as a measure of its salinity.
