Question

The salinity of ocean water is measured in parts per thousand. Therefore, if the salinity of 500g of saltwater is 30ppt, there are 15g of dissolved salts in the seawater (1/2 of 30ppt = 15g). If the average salinity of seawater is 35ppt, how many grams of dissolved salts will 500g of seawater contain?
