Answer:
The answer is
<h2>4.0 g/cm³</h2>
Explanation:
The density of a substance can be found by using the formula
<h3>

</h3>
From the question
mass of block = 36 g
volume = 9 cm³
The density is

We have the final answer as
4.0 g/cm³

Answer: The given substances are placed in order from most soluble in water to least soluble in water as follows.

> 
Explanation:
It is known that like dissolves like which means a polar compound will be soluble in a polar solvent. And, a non-polar compound will be soluble in non-polar solvent.
Ionic compounds are soluble in polar solvent like water. For example,
is an ionic compound and it is readily soluble in water.
2-butanol (
) is also a polar compound and it will also dissolve in water but to a lesser extent as compared to magnesium chloride.
Whereas both methane and propane are non-polar in nature. But as propane is larger in size as compared to methane so, it will be slightly more soluble in water as compared to methane.
Thus, we can conclude that the given substances are placed in order from most soluble in water to least soluble in water as follows.

Answer:
10/24
Simplified: 5/12
Explanation:
Well first, let's convert years into months
1 year = 12 months which means 2 years = 24 months
In fraction form we would write this as 10/24
If the question asks for it to be simplified, then simply
Both 10 and 24 evenly fit 2
Therefore, divide both the numerator and the denominator by 2
10 ÷ 2 / 24 ÷ 2
5/12
This can no longer be simplified
The first one would be it
Answer: If you think about it, B. would be the most reasonable answer with the given factors.
