Answer:
moles gaseous reactants will be doubled
Step-by-step 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.
