From the experiments conducting 2 trials
The average total dissolve solids of sample is 2g/kg ppt
average total solid of sample is 1.4
total suspended solid of sample is -0.05
the above sample results are from one students 4 students conducted the same expriments with different samples
The total dissolved solids done by 4 students : the no:3 student has the highest value:37.5g/kg
The total solids : no3 student has a highest value: 4.50g/kg
The totla suspended soil : no3 has high value : 34g/kg
Finally the average total suspended solids of the 4 students is 8.3g/kg
8.3g/kg is the average dry weight of the sample
