The volume of the entire object
Answer:
See Explanation
Explanation:
We can establish that there are chloride ions present in water if we add dilute trioxonitrate V acid to a sample of the water in drops followed by aqueous silver trioxonitrate V.
If a white precipitate is observed and the precipitate is found to be soluble in excess aqueous ammonia solution, then we can confirm the presence of chloride ion in the water.
Answer:
1) The vapor density of the organic compound is approximately 12.57
2) The relative molar mass (RMM) of the organic compound is approximately 25.14 grams
Explanation:
1) The mass of the balloon filled with dry hydrogen = 35 grams
The mass of the balloon filled with vapor of an organic compound = 440 grams
The vapor density = (Weight of a given volume of gas)/(Weight of equal volume of hydrogen)
The vapor density of the organic compound = (440)/(35) ≈ 12.57
The vapor density of the organic compound ≈ 12.57
2) The relative molar mass (RMM) = 2 × vapor density
The relative molar mass (RMM) of the organic compound = 2 × vapor density of the organic compound
The relative molar mass (RMM) of the organic compound ≈ 2 × 12.57 ≈ 25.14 grams
The relative molar mass (RMM) of the organic compound ≈ 25.14 grams
Answer:
The answer to your question is 11.0 L
Explanation:
Data
[Concentration 1] = 12 M
Volume 1 = 3.0 L
[Concentration 2] = 3.25 M
Volume 2 = ?
Process
1.- To solve this problem, use the dilution formula
Concentration 1 x Volume 1 = Concentration 2 x Volume 2
- Solve for Volume 2
Volume 2 = Concentration 1 x Volume 1 / Concentration 2
- Substitution
Volume 2 = 12 x 3 / 3.25
- Simplification
Volume 2 = 36 / 3.25
- Result
Volume 2 = 11 L
Water is a pure substance because it is not refined like the other materials. Hope this helps!!!
