What is the number of moles of H2 produced when 23 grams of sodium reacts with water?
The answer is o,5 mol.
What happens to the volume of the gas when the number of moles is doubled?
The ideal Gas Law states the following:
pV=nRT
p=pressure [pa]
V=volume [m³]
n=number of moles
R=constant
T=temperature [K]
So, if you multiply the number of moles by 2, and all the other variables are not changed, your volume will also be multiplied by 2.
These data are given by the correct coefficients in the chemical equation.
