A 25.0 mL aliquot of a well-shaken and filtered sample of river is pipetted into an evaporating dish. The sample was heated to dryness. Assume the density of the river water was 1.01g/mL. The following data were collected for Trial 1. Complete the data. Record values with the correct number of significant figures.
1. Mass of evaporating dish (g)
2. Mass of water sample plus evaporating dish (g):
3. Mass of water sample (g)
4. Mass of dried sample plus evaporating dish (g)
5. Mass of dissolved solids in 25-mL aliquot of filtered sample (g)
6. Mass of dissolved solids per total mass of sample (g solids/ g sample) show calculation..HOW DO I FIND THIS?
7. Total solids (g solids/ g sample, ppt).
