Taking into account the definition of density, the density of the liquid is 0.76 [tex]\frac{g}{mL}[/tex].
First of all, 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:
[tex]density=\frac{mass}{volume}[/tex]
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.
In this case, you know:
mass= 19 gvolume =25 mLSo, replacing in the definition of density:
[tex]density= \frac{19 g}{25 mL}[/tex]
Solving:
[tex]density= 0.76 \frac{g}{mL}[/tex]
Finally, the density of the liquid is 0.76 [tex]\frac{g}{mL}[/tex].

An element has an atomic number of 16. An ion of this element has a 2-charge. How was the ion formed?
Answer: The answer is ‘a neutral atom gained 2 electrons’
Explanation: Because electrons are negatively charged and adding 2 extra would make the ion negatively charged by 2

Based on the equation, how many grams of Br2 are required to react completely with 36.2 grams of AlCl3? 2AlCl3 + 3Br2 → 2AlBr3 + 3Cl2 (5 points)
a) 65.2 grams
b) 69.8 grams
c) 72.1 grams
d) 76.5 grams
Explanation:
basically, you'll just have to convert the given grams into moles, convert that into moles of Br, and then convert it again into grams of Br
The amount of gram of [tex]Br_{2}[/tex] will be 65.1 grams in equation [tex]2AlCl_{3} + 3Br_{2}[/tex]→ [tex]2AlBr_{3} + 3Cl_{2}[/tex].
What is gram?The definition of a gram was given as the mass of one cubic centimeter of pure water at 4 degrees Celsius.
Calculation of amount of [tex]Br_{2}[/tex]
The given equation is [tex]2AlCl_{3} + 3Br_{2}[/tex]→ [tex]2AlBr_{3} + 3Cl_{2}[/tex].
The mass of [tex]Br_{2}[/tex] = Count of bromine molecule × molar mass
The mass of [tex]Br_{2}[/tex] = 0.4072 × 159.8
The mass of [tex]Br_{2}[/tex] = 65.08 mol.
The amount of gram of [tex]Br_{2}[/tex] will be 65.1 grams in equation [tex]2AlCl_{3} + 3Br_{2}[/tex]→ [tex]2AlBr_{3} + 3Cl_{2}[/tex].
Therefore, the answer will be option (a).
