Explanation:
1.
Sodium, or Na, is 57.47% of the composition,
Hydrogen, or H, is 2.520% of the composition,
and Oxygen, or O, is 40.001% of the composition.
This is because mass% = mass/total mass x 100%.
2. For every 1 mole of C6H12O6, you need 6 moles of water. Multiply the 5.2 moles you are trying to make by the 6 moles of water you need, and you will need 31.2 moles.
3. x = 7.2 x 4 / 2 = 14.4 mol
Electrons are located in the orbits around the nucleus... we can name them as shells K,L,M,N...
Answer:
The empirical formula is C3H3O
Explanation:
Step 1: Data given
Suppose the mass of the molecule = 100 grams
The molecule contains:
65.5 % Carbon = 65.5 grams
5.5 % Hydrogen = 5.5 grams
29.0% Oxygen = 29.0 grams
Molar mass of C = 12 g/mol
Molar mass of H = 1.01 g/mol
Molar mass of O = 16 g/mol
Step 2: Calculate moles
Moles = mass / molar mass
Moles C = 65.5 grams / 12 g/mol = 5.46 moles
Moles H = 5.5 / 1.01 g/mol = 5.45 moles
Moles O = 29.0 grams / 16 g/mol = 1.8125 moles
Step 3: Calculate mol ratio
We divide by the smallest amount of moles
C: 5.46 / 1.8125 = 3
H = 5.45 / 1.8125 = 3
O = 1.8125/1.8125 = 1
The empirical formula is C3H3O

I would say it’s the last answer . D. I would say this because the Germans took the Jews belongings like gold, money, jewelry, anything they had and they kept it to themselves so the Jews didn’t have anything valuable . Even their clothes.
