Answer:
Read what Archimedes did. Look it up.
Explanation: You need to read!
The point is, what is the volume of the cube! If you took the cube out, wouldn’t the water level drop? How much? The volume of the cube!
To find the density, I always say, "density is a broken heart". The reason is that it's mass over volume.
Ex: D = m/ v
In your problem, it's:
D = 632g/ 680 mL
To find the density of the Linseed oil, divide the volume by mass.
680mL/ 632g = 1.07
Now that you have your answer, you need to have the correct units. Since you have two different units, you'd use those both. So, your answer will be grams over mL.
The density of the Linseed oil is 1.07g/mL
I hope I helped :)
An ionic bond is a type of chemical bond formed through an electrostatic attraction between two oppositely charged ions. Ionic bonds are formed between a cation, which is usually a metal, and an anion, which is usually a nonmetal. A covalent bond involves a pair of electrons being shared between atoms
Answer:
The final volume is 6.4 L.
Explanation:
Dilution is reducing the concentration of a chemical and is achieved by adding more solvent to the same amount of solute. In other words, dilution is the procedure that is followed to prepare a less concentrated solution from a more concentrated one, and it simply consists of adding more solvent.
In a dilution the amount of solute does not vary, and as only more volume (and mass) of solvent is being added, the concentration of the solute decreases.
In a dilution the expression is used:
Ci*Vi = Cf*Vf
where:
- Ci: initial concentration
- Vi: initial volume
- Cf: final concentration
- Vf: final volume
In this case:
- Ci: 8 M
- Vi: 2 L
- Cf: 2.5 M
- Vf: ?
Replacing:
8 M* 2 L= 2.5 M* Vf
Solving:
Vf=6.4 L
<u><em>The final volume is 6.4 L.</em></u>
