Question

Complete the last two columns given the data already present in the table.

A researcher wishes to determine how the water absorption capacity of sodium polyacrylate varies as a function of lithium ion (Li⁺) concentration. The researcher has recorded the following:

Concentration of LiNO3 Solution	Mass of Sodium Polyacrylate (g)	Incubating Volume of LiNO3 Solution (mL)	Volume of Filtrate Collected (Unabsorbed LiNO3 Solution) (mL)	Volume of LiNO3 Solution Absorbed by Sodium Polyacrylate (mL)	Volume (mL) of Water Absorbed per Gram of Sodium Polyacrylate
0.020	0.101	40.0	30.6
0.015	0.098	40.0	30.3
0.010	0.103	40.0	28.9
0.0050	0.095	40.0	27.6
0.0025	0.099	40.0	23.4
0.00	0.104	40.0	15.5

Answer 1

:

Concentration of LiNO3 Solution	Mass of Sodium Polyacrylate (g)	Incubating Volume of LiNO3 Solution (mL)	Volume of Filtrate Collected (Unabsorbed LiNO3 Solution) (mL)	Volume of LiNO3 Solution Absorbed by Sodium Polyacrylate (mL)	Volume (mL) of Water Absorbed per Gram of Sodium Polyacrylate
0.020	0.101	40.0	30.6	40.0-30.6=9.4 ml	9.4 ml/0.101g=93.069 ml/g
0.015	0.098	40.0	30.3	40.0-30.3=9.7 ml	9.7/0.098=98.98 ml/g
0.010	0.103	40.0	28.9	40.0-28.9=11.1ml	11.1/0.103=107.77ml/g
0.0050	0.095	40.0	27.6	40.0-27.6=12.4 ml	12.4ml/0.095g=130.53ml/g
0.0025	0.099	40.0	23.4	40.0-23.4=16.6 ml	16.6ml/0.099 g=167.68 ml/g
0.00	0.104	40.0	15.5	40.0-15.5=24.5 ml	24.5ml/0.104g=235.58 ml/g
