Answer: these are the values of density that complete the table
Sample density
A 1024 B 1027 C 1026 D 1025 E 1028
Procedure: take the values of temperature and salinity for each sample given in the table, and enter the graph to read the corresponding density value.
1) Sample A: temp = 21°C, salinity = 34%
Locate the value 34 on the horizontal axis (salinity axis), move vertically upward until reaching the level of 21 for the vertical axis, read the value of the density on the curve that passes through the point (34, 21). That value is density = 1024 g/cm^3.
That is the value to copy on the table.
2) Sample B: temp = 11°C, salinity =35 %
Locate the value 35 on the horizontal axis (salinity axis), move
vertically upward until reaching the level of 11 for the vertical axis,
read the value of the density on the curve that passes through the point
(35, 11). That value is density = 1027 g/cm^3.
That is the value to copy on the table.
3) Sample C: temp = 12°C, salinity = 34%
Locate the value 34 on the horizontal axis (salinity axis), move
vertically upward until reaching the level of 12 for the vertical axis,
read the value of the density on the curve that passes through the point
(34, 12). That value is density = 1026 g/cm^3.
That is the value to copy on the table.
4) Sample D: temp = 19°C, salinity = 35%
Locate the value 35 on the horizontal axis (salinity axis), move
vertically upward until reaching the level of 19 for the vertical axis,
read the value of the density on the curve that passes through the point
(35, 19). That value is density = 1025 g/cm^3.
That is the value to copy on the table.
5) Sample E: temp = 3°C, salinity = 35%
Locate the value 35 on the horizontal axis (salinity axis), move
vertically upward until reaching the level of 3 for the vertical axis,
read the value of the density on the curve that passes through the point
(35, 3). That value is density = 1028 g/cm^3.
