Taking into account the definition of density, the mass of a substance with a volume of 150 cm³ and a density of 1.5
is 225 grams.
<h3>What is density</h3>
Density is defined as the property that matter, whether solid, liquid or gas, has to compress into a given space.
In other words, density is a quantity that allows us to measure the amount of mass in a certain volume of a substance.
Then, the expression for the calculation of density is the quotient between the mass of a body and the volume it occupies:

From this expression it can be deduced that density is inversely proportional to volume: the smaller the volume occupied by a given mass, the higher the density.
<h3>Mass of the substance in this case</h3>
In this case, you know that:
- Density= 1.5

- Volume= 150 cm³
Replacing in the definition of density:

Solving:
mass= 1.5
×150 cm³
<u><em>mass= 225 g</em></u>
In summary, the mass of a substance with a volume of 150 cm³ and a density of 1.5
is 225 grams.

Answer:
2 i think should be the correct answer
Explanation:
The boiling point of the calcium chloride CaCl2 solution will be higher than that of the boiling point of the sodium chloride NaCl solution, because more molecules are present in the CaCl2 solution since CaCl2 dissociates into three ions while NaCl only dissociates into two ions.
Answer: The percent dissociation of 4-chlorobutanoic acid is 21%
Explanation:
The dissociation of weak acid is shown as:

cM 0 0

So dissociation constant will be:

Give c= 0.54 mM =
and
= ?

Putting in the values we get:



Thus the percent dissociation of 4-chlorobutanoic acid is 21%
