Hello!
Similarities:
-They can conduct electric current because they both are ionic substances.-
-They both form Water and Salt when neutralized.
Differences:
-Acids release Hydronium ions (H₃O⁺) when hydrolyzed while Bases release Hydroxyl ions (OH⁻) when hydrolyzed.
-Acids are commonly formed with non-metals (such as Chlorine, Sulfur, Oxygen, and Nitrogen) while Bases are commonly formed with metals (such as Sodium, Potassium, Calcium, and Copper).
Have a nice day!
Answer:
If you are given with the atomic number of an element you can find it's period number and group number. The period number is related to the number of electron occupied shells in the element and the period number is linked to its valence electrons.

You forgot to include the known characteristics of the solution.
I searched them and copy here:
volume: 1.000 liter
M = 0.0190 M
Now, you can start with the definition of mass percent.
mass percent = (grams of solute / grams of solution) * 100
grams of solute are obtained from the molar concentration:
M = (number of moles of solute) / (volume of solution in liters)
where number of moles = (grams) / (molar mass)
=> M = (grams of solute / molar mass of solute) / (volume of solution in liters)
=> grams of solute = M * (volume of solution in liters) * (molar mass of solute)
And density = (kg of solution / volume of solution in liters) =>
kg of solution = density * volume of solution in liters
grams of solution = density * (volume of solution in liters) * 1000 g/kg
=> mass percent = M * (volume of solution in liters) * (molar mass) / (density * volume of solution in liters * 1000 g/ kg) * 100
=> mass percent = M * molar mass * 10 / density
now replace the values known:
M = 0.0190 mol / liter
density = 1,000 kg / liter
molar mass of Ba(NO3)2 = 137.327 g/mol + 2*14.007 g/mol + 2*3*15.999 g/mol = 256.335 g/mol
=> mass percent = 0.0190 mol/liter * 256.335 g/mol * 10 kg/ g / (1.000 kg/liter)
=> mass percent = 48.7%
Isomer types. The connectivity and molecular motion due to bond rotations within a molecule can result in atoms that are considered to be equivalent or non-equivalent types. For example, the six hydrogen atoms in ethane are considered to be chemically equivalent
