 Step 1 ??? Calculate the total dissolved solids in the water sample in mg/l (p.p.m.) Evaporate to dryness in a dust-free oven at 105 degrees Celsius Add 100 cm3 of a filtered water sample to the beaker Find the mass of the cooled dry beaker Find the mass of a clean dry 250 cm³ beaker Step 2 ??? Calculate the total dissolved solids in the water sample in mg/l (p.p.m.) Evaporate to dryness in a dust-free oven at 105 degrees Celsius Add 100 cm3 of a filtered water sample to the beaker Find the mass of the cooled dry beaker Find the mass of a clean dry 250 cm³ beaker Step 3 ??? Calculate the total dissolved solids in the water sample in mg/l (p.p.m.) Evaporate to dryness in a dust-free oven at 105 degrees Celsius Add 100 cm3 of a filtered water sample to the beaker Find the mass of the cooled dry beaker Find the mass of a clean dry 250 cm³ beaker Step 4 ??? Calculate the total dissolved solids in the water sample in mg/l (p.p.m.) Evaporate to dryness in a dust-free oven at 105 degrees Celsius Add 100 cm3 of a filtered water sample to the beaker Find the mass of the cooled dry beaker Find the mass of a clean dry 250 cm³ beaker Step 5 ???
