I found a similar question online which will help me answer your incomplete question. To make it easier, show all the elements of the compound given. It is shown in the second picture attached.
a.) The formula for unsaturation number is shown in the 3rd picture attached. Following this,
n = 8
m = 2(8) + 2 + 0 + 0 - 0 = 18
Thus,
x = Unsaturation number = (18 - 8)/2 = 5
<em>The unsaturation number is 5.</em>
b.) The molar mass of C is 12.01 g/mol; H is 1 g/mol; O is 16 g/mol. So, the molecular weight is:
Molecular weight = 12.01(8) + 8(1) + 2(16) = 136.08 g/mol
<em>The molecular weight of the ester is 136.08 g/mol.</em>

Answer:
6
Explanation:
Formula: Al2O3
If we require 2Al2O3
We divide 2 by 3

Answer: Option 1, 4 and 5 describe acids accurately.
Explanation:
Option 1: Acids have a sour taste because of the concentration of ion.
Option 2: They are corrosive in nature, that is they are not at all gentle with the skin and fabric as some acids intend to burn skin such as is a strong acid which can burn skin as well as fabric.
Option 3: Acids need electrons to release ions and non-metals do not donate electrons hence, there is no reaction between a non-metal and an acid.
Option 4: All acids do contain hydrogen. They dissociate in the presence of water to produce ions.
Option 5: Acids do conduct electricity that is they carry electrical charges. This was explained by Arrhenius. He said that the acids dissociate into ions, when it is dissolved in water. These ions hence acts as charge carriers in water.
