Answer:

moles gaseous reactants will be doubled

Explanation:

Avogadro's law about ideal gas can be presented as PV=nRT where P is pressure, V is volume, n is the number of molecules, R is constant, and T is temperature.

The question asks how many molecules of gas reactant (n) so we can tweak the formula into n=...

PV=nRT

n=PV/RT

Pressure, constant and temperature are the same so we can remove it from the equation.

n= V

The volume is directly proportional to the number of molecules. If the volume is doubled then (V2= 2*V1), then the number of the molecule(n) needed will be doubled too.
