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].

Explanation:
In store A: A box of cotton candy costs 1 dollar, 12 boxes cost 12 dollars. In store B: 12 boxes cost 48 dollars. How much does each box cost in store B?
Answer:
4
Explanation:
If there is 12 boxs that cost $48, you need to divide the 12 boxs into the $48 to see how many time 12 goes into it to see how much it is. So 48 divided by 12 is 4.

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].
