Answer:
For the first question, to determine the total number of molecules of nitrogen dioxide, first make use of the molar mass of the nonpolar compound and then use that to find the total number of moles and then subsequently after make use of the ratio for the Avogadro's number to determine the total number of molecules of this compound.
For the final question, do the inverse, where we make use of the molecules of the compound and then use Avogadro's number to determine the moles of the compound and then use the same molar mass of the compound to determine the grams of the Nitrogen Dioxide.
Hello!
The general chemical equation for the neutralization of an acid HA with NaOH is the following:
HA(aq) + NaOH(aq) → NaA(aq) + H₂O(l)
For determining the concentration of the acid solution, we can use the equation shown below:
So, the concentration of the Acid is
