Answer:
11.5moles of oxygen gas
Explanation:
The reaction equation is shown below;
C₂H₆O + 3O₂ → 2CO₂ + 3H₂O
We were given 11.5moles of H₂O produced;
Since the equation is balanced;
3 mole of oxygen gas was used to produce 3 mole of water
11.5 moles of water will be produced 
= 11.5moles of oxygen gas

Answer:
O the molecular formula
Explanation:
The true ratio of atoms in a molecule or formula unit is called the molecular formula.
The molecular formula of a compound shows the true number of atoms that are combining to form a compound.
For example, the molecular formula of water is H₂O.
- Empirical formula of a compound is its simplest ratio.
- When the number of atoms are divided by the smallest possible factor, it yields the empirical formula.
Answer:
The "unit" remaining after conversion is atoms.
This is a way to calculate the number of atoms, in an specific mass.
Explanation:
When you have a mass, multiplying the molar mass, "grams" are cancelled, so you finally obtained, number of moles.
Moles . atoms/mol, cancel the word mol so you will find out a number of atoms, present at the mass from, the begining.
For example, how many atoms are in 10 g of NaCl
Molar mass NaCl = Na mass + Cl mass
23 + 35.45 = 58.45 g/m
10 g . 1 / 58.45 mol/g . NA/ 1 mol = 3.42x10²⁰ atoms
NA = Avogadro number
The symbols indicate the physical state of each reactant
