Hi there,
NH3 has the weight of 17.03 grams, and SF6 has the weight of 146.06 grams
so in total, there is 163.09 grams
Hope this helps :P
First we must write a balanced chemical equation for this reaction

The mole ratio for the reaction between
and
is 1:2. This means 1 moles of
will neutralize 2 moles
. Now we find the moles of each reactant based on the mass and molar mass.



The
was enough to neutralize the acid because 18.87:39.67 is the same as 1:2 mol ratio.
It is not correct to say " a molecule of salt " because salt is a compound.
Explanation:
- As we know a molecular bond is present in each molecule.
- Salt (NaCl) is considered as a compound because it is made up of two types of elements that are sodium as well as chlorine.
- On the other hand it is not considered as a molecule as it is not holding an ionic bond.
- As a result we can name it as an ionic compound. Hence it is not considered as a molecule of salt.
