bar by selecting or by getting them from another browser. Import your favorites D Question 4 3 pts Use the following information to answer the next three questions. A water sample was collected at Dash Point (in Federal Way, WA, just south of Seattle) and evaporated. The original sample's mass was 840 grams, and it yielded 21 grams of salts when dried. (HINT: Even if you're not sure how to do the first part of this question, you can try the other parts- Just be sure to explain your assumptions.) Calculate the salinity of the sample. Show all work, including units for every term in every step! HTML Editor Paragraph Mass of sea water collected = 840gm Mass of salt after evaporation of water 21gm Salinity = Amount of Salt/ Amount of sea water = 21 gm/ 840 gm = 0.025-2.5 %

Explanation / Answer

The salinity value calculated in the previous question was 2.5%. But, the normal value of salinity in ocean water equals 3.5%. So, this salinity value is lower than the expected value.
