A 24.0 gram object has a volume of 6.0 mL. What is the density of the object?
2 answers:
Answer:
4 g/mL
Explanation:
The density of a object can be found using the following formula.
where m is the mass and v is the volume.
We know that the mass of the object is 24.0 grams and the volume is 6.0 milliliters.
Substitute the values into the formula.
Divide 24 g by 6 mL.
The density of the object is 4 grams per milliliter.

Here's what I get
Explanation:
1. Water
The O-H bond in water is highly polar.
It has about one-third ionic character.
The partially-positive H atoms and partially negative O atoms strongly attract each other by hydrogen bonds.
It takes a large amount of energy to separate the water molecules from each other.
Thus, the boiling point of water is relatively high (100 °C).
2. Acetone
The C=O bond in acetone is much less polar.
It is less than 20 % ionic.
The dipole-dipole attractions in acetone are much weaker than the hydrogen bonds in water.
It takes much less energy to separate the acetone molecules from each other.
Thus, even though the molar mass of acetone is more than three times that of water, the boiling point of acetone is only 56 °C.
