Answer: The molecular formula will be C_3H_9

Explanation:

Molecular formula is the chemical formula which depicts the actual number of atoms of each element present in the compound.  

Empirical formula is the simplest chemical formula which depicts the whole number of atoms of each element present in the compound.  

The empirical formula is CH_3

The empirical weight of CH_3 = 1(12)+3(1)= 15g.

The molecular weight = 45.0 g/mole

Now we have to calculate the molecular formula:

n=\frac{\text{Molecular weight }}{\text{Equivalent weight}}=\frac{45}{15}=3

The molecular formula will be=3\times CH_3=C_3H_9

Thus molecular formula will be C_3H_9

In the balanced equation (picture included) how many moles of O2 MOLECULES and O2 ATOMS react?
tangare [24]

1) The answer is: 2 moles of oxygen molecules.

Balanced chemical reaction of methane combustion:  

CH₄(g) + 2O₂(g) → CO₂(g) + 2H₂O(g).

Coefficients with the lowest ratio indicate the relative amounts of substances in a reaction.

In fronf of oxygen molecule is coefficient 2.

2) The answer is: 4 moles of oxygen atoms.

In one molecule of oxygen there are two oxygen atoms, so in two molecules there are four oxygen atoms.
