The answer is:
The empirical formula is the option B.
The empirical formula of a compound is the simplest formula that can be written. On the opposite, the molecular formula involves a variant of the same compound, but it can be also simplified to an empirical formula.
We are looking for a formula that cannot be simplified by dividing the number of molecules/atoms that conforms the compound.
Let's discard option by option in order to find which formula is an empirical formula (cannot be simplified)
A.
It's not an empirical formula, it's a molecular formula since it can be obtained by multiplying the empirical formula of the same compound.
B.
It's an empirical formula since it cannot be obtained by the multiplication of a whole number and the simplest formula. It's the simplest formula that we can find of the compound.
C.
It's not an empirical formula, it's a molecular formula since it can be obtained by multiplying the empirical formula of the same compound.
D.
It's not an empirical formula, it's a molecular formula since it can be obtained by multiplying the empirical formula of the same compound.
Hence, the empirical formula is the option B.

Answer: A. 1.60 liters
Explanation:
As can be seen from the balanced chemical equation, 2 moles of produce 1 mole of
.
According to Avogadro's law, every 1 mole of the gas occupies 22.4 liters at STP.
Thus moles of
occupies
at STP and produce 1 mole of
i.e. 22.4 L
44.8 L of will produce 22.4 L of
Thus of
will produce
