Answer:
Molecular Formula = C₄O₂H₈
Explanation:
Molecular formula is calculated from following formula.
Molecular Formula = n(Empirical formula)
The formula for n is given as,
n = Molecular Formula Mass / Empirical Formula Mass
Molecular Formula mass = 88 g/mol
Empirical formula mass = 44
Putting values,
n = 88 / 44 = 2
Now,
Molecular Formula = 2(C₂OH₄)
Molecular Formula = C₄O₂H₈

<u>Answer:</u> The amount of pure antifreeze that must be added is 6.4 gallons
<u>Explanation:</u>
We are given:
Percent of antifreeze given = 10 %
Amount of solution = 8 gallons
Let the amount of pure antifreeze be 'x'
Calculating the amount of pure antifreeze:

Let the amount of pure antifreeze added in the solution be 'y'
Percent of solution to be made = 50 %
So,

Hence, the amount of pure antifreeze that must be added is 6.4 gallons
Answer:
374 atoms would be present in 22 units of aluminum sulfate.
Explanation:
Formula for Aluminium Sulfate : Al₂(SO₄)₃
Al = 2
S = 1
O = 4
(SO) = 3
∴ Number of atom in one unit is : 2 + (1+4)3 ==> 17
If there are 17 atoms in one unit, therefore;
Number of atoms in 22 units = 17 x 22
= 374 atoms
