To find the number of atoms in 3.90 moles of sulfur (S), multiply the number of moles by Avogadro's number, which is approximately 6.022 x 10^23 atoms per mole. This calculation yields about 2.35 x 10^24 atoms of sulfur. Understanding the relationship between moles and Avogadro's number is crucial for solving such problems. The periodic table provides essential information about the element, but the key is applying the mole-to-atom conversion. This method is fundamental in chemistry for quantifying substances at the atomic level.

[![question with rate laws][1]][1]
Now the rate law for the reaction (i.e reaction rate) can be written as:
$$ R= k[N_2O_5] $$
my main question is, WHAT is this reaction equal to?
what I mean here is, whether
$$k[N_2O_5]= -d[N_2O_5]/dt$$
or is it
$$k[N_2O_5]= -1/2 \frac{d}{dt} [N_2O_5] $$ ?
The latter seems to be more apt, as the reaction rate must be -1/2 (disappearance rate of N2O5), which adheres to the stoichiometry of the...
