how do you find the mass of dehydrated sample?
mass of crucible and cover- 30.95 g
mass of hydrated sample, crucible, and cover- 32.75 g
mass of hydrated sample-?
mass of dehydrated sample, crucible and cover- 1st weighing-32.47 g
mass of dehydrated sample, crucible, and cover 2nd weighing-32.48 g
mass of dehydrated sample:?
mass dehydrated sample is
mass sample + container after heating
- mass sample + container before heating
To find the mass of the dehydrated sample, you can subtract the mass of the crucible and cover from the mass of the dehydrated sample, crucible, and cover.
1. First, determine the mass of the dehydrated sample, crucible, and cover by subtracting the mass of the crucible and cover from the mass of the hydrated sample, crucible, and cover:
Mass of dehydrated sample, crucible, and cover = Mass of hydrated sample, crucible, and cover - Mass of crucible and cover
Mass of dehydrated sample, crucible, and cover = 32.75 g - 30.95 g = 1.8 g
2. Next, use the two weighing measurements of the dehydrated sample, crucible, and cover to calculate the mass of the dehydrated sample.
Mass of dehydrated sample = Second weighing measurement - First weighing measurement
Mass of dehydrated sample = 32.48 g - 32.47 g = 0.01 g
Therefore, the mass of the dehydrated sample is 0.01 g.
