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! Mass of sea water collected 840gm Mass of salt after evaporation of water 21gm Salinity = Amount of Sat / Amount of sea water -21 gm/ 840 gm 0.025-2.5 %

Explanation / Answer

The correct option is lower than.

The average sea-water salinity is 3.5 %. In this case, the obtained salinity in problem 4 is lower than the average seawater salinity.
