Answer is: <span>concentration of fluoride in the water in parts-per-million is 1 ppm.
</span>Parts-per-million (10⁻⁶) is<span> present at one-millionth of a </span>gram per gram of sample solution, f<span>or example mg/kg.
</span>m(fluoride) = 500 g · 1000 mg/g = 500000 mg.
m(water) = d(water) · V(water).
m(water) = 1 kg/L · 500000 L.
m(water) = 500000 kg.
arts-per-million = 500000 mg ÷ 500000 kg = 1 mg/kg = 1 ppm.
This is what I found!!! I hope this helps!!!!

Answer:
2HCl is the product of this reaction 2 is added in order to balance the reaction
Explanation:
Organic compounds are defined as the compounds which contain carbon as their main element. For example, 
is an organic compound.
Generally, organic compounds are non-polar in nature and due to the presence of covalent bonding organic compounds have low melting point.
As compound A melts at 
and is soluble in water. This means it is an ionic compound as it has high melting point and it is also polar in nature.
Whereas compound B melts at 
and is insoluble in water. This means that this compound has covalent bonding and it is also non-polar in nature
. Hence, it is more likely to be organic in nature.
Thus, we can conclude that compound B is more likely to be an organic
compound.
